Contoh Soalan dan Penyelesaian: Ekspresi Algebra

Alright, let's get our hands dirty with some Contoh Soalan Algebra Tingkatan 4! We'll start with algebraic expressions. These are combinations of numbers, variables (like x and y), and mathematical operations (+, -, ×, ÷). Here's a typical question type and how to solve it:

Soalan 1: Simplify the expression: 3(2x + 4) - 2(x - 1)

Penyelesaian:

  1. Expand the brackets: Multiply the numbers outside the brackets by each term inside. This gives us:
    • 3 * 2x = 6x
    • 3 * 4 = 12
    • -2 * x = -2x
    • -2 * -1 = +2 So, the expression becomes: 6x + 12 - 2x + 2.
  2. Collect like terms: Combine the terms with 'x' and the constant terms separately.
    • 6x - 2x = 4x
    • 12 + 2 = 14
  3. Final answer: The simplified expression is 4x + 14.

See? Not so hard, right? The key is to follow the order of operations (PEMDAS/BODMAS) and be careful with the signs. Another common type of question involves factorizing algebraic expressions. Factorizing is like doing the opposite of expanding. Here's an example:

Soalan 2: Factorize the expression: 15x + 10

Penyelesaian:

  1. Find the greatest common factor (GCF): Look for the largest number that divides both terms. In this case, it's 5.
  2. Factor out the GCF: Divide each term by the GCF and write the GCF outside the brackets.
    • 15x ÷ 5 = 3x
    • 10 ÷ 5 = 2 So, the factorized expression is 5(3x + 2).

Factorizing can sometimes be a bit tricky, especially with quadratic expressions. However, with practice, you'll get the hang of it. Remember to always check your answer by expanding the factorized expression to see if it matches the original one. We'll cover more complex factorizing examples later on. Don't worry if it takes a while to grasp the concepts. Practice makes perfect, and with each Contoh Soalan Algebra Tingkatan 4 you solve, you'll gain confidence and understanding. Keep practicing and applying these steps, and you will become proficient in algebraic expressions. Ready to move on? Let's keep exploring the realm of algebra.

Contoh Soalan dan Penyelesaian: Persamaan Linear

Now, let's explore Contoh Soalan Algebra Tingkatan 4 involving linear equations. Linear equations are equations that can be written in the form of ax + b = c, where a, b, and c are constants, and x is the variable. The goal is to find the value of x that satisfies the equation. Here are a couple of examples:

Soalan 3: Solve for x: 2x + 5 = 11

Penyelesaian:

  1. Isolate the term with x: Subtract 5 from both sides of the equation.
    • 2x + 5 - 5 = 11 - 5
    • 2x = 6
  2. Solve for x: Divide both sides by 2.
    • 2x / 2 = 6 / 2
    • x = 3

So, the solution to the equation is x = 3. See? Easy peasy! The key is to perform the same operation on both sides of the equation to keep it balanced. Let's try another one that's a bit more challenging.

Soalan 4: Solve for x: 3(x - 2) = 9

Penyelesaian:

  1. Expand the brackets: Multiply the 3 by each term inside the brackets.
    • 3 * x = 3x
    • 3 * -2 = -6 So, the equation becomes: 3x - 6 = 9.
  2. Isolate the term with x: Add 6 to both sides.
    • 3x - 6 + 6 = 9 + 6
    • 3x = 15
  3. Solve for x: Divide both sides by 3.
    • 3x / 3 = 15 / 3
    • x = 5

Therefore, the solution is x = 5. Another common type of question involves word problems that require you to create and solve linear equations. These problems test your ability to translate real-world scenarios into mathematical equations. We'll look at some examples of those later. Remember, always check your answer by substituting the value of x back into the original equation. If both sides of the equation are equal, then your solution is correct. Keep practicing with different types of linear equations and word problems, and you'll become a pro at solving them. You're doing great, keep going!

Contoh Soalan dan Penyelesaian: Ketaksamaan Linear

Let's move on to Contoh Soalan Algebra Tingkatan 4 on linear inequalities. Inequalities are similar to equations, but instead of an equals sign (=), they use symbols like < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to). The rules for solving linear inequalities are almost the same as for equations, with one important difference: If you multiply or divide both sides of an inequality by a negative number, you must flip the inequality sign.

Soalan 5: Solve for x: 2x - 3 < 5

Penyelesaian:

  1. Isolate the term with x: Add 3 to both sides.
    • 2x - 3 + 3 < 5 + 3
    • 2x < 8
  2. Solve for x: Divide both sides by 2.
    • 2x / 2 < 8 / 2
    • x < 4

So, the solution is x < 4. This means that x can be any number less than 4. Now, let's look at another example with a negative number:

Soalan 6: Solve for x: -3x + 2 ≥ 8

Penyelesaian:

  1. Isolate the term with x: Subtract 2 from both sides.
    • -3x + 2 - 2 ≥ 8 - 2
    • -3x ≥ 6
  2. Solve for x: Divide both sides by -3. Remember to flip the inequality sign because we're dividing by a negative number.
    • -3x / -3 ≤ 6 / -3
    • x ≤ -2

Therefore, the solution is x ≤ -2. The key here is to pay close attention to the direction of the inequality sign and to remember to flip it when multiplying or dividing by a negative number. Linear inequalities are used in various real-world applications, such as setting constraints on variables and defining feasible regions. Practicing these problems will not only boost your algebra skills but also your problem-solving abilities in other areas. Keep up the great work! You're on the right track.
