Q. Find the value of x in the equation 3x^2 - 12 = 0.

A. -2
B. 2
C. 4
D. 0

Solution

Add 12 to both sides: 3x^2 = 12. Divide by 3: x^2 = 4. Thus, x = ±2.

Correct Answer: B — 2

Q. Find the value of x in the equation 4x^2 + 8x + 3 = 0.

A. x = -1
B. x = -3/2
C. x = -1/2
D. x = -3

Solution

Using the quadratic formula x = [-b ± √(b² - 4ac)] / 2a gives x = [-8 ± √(64 - 48)] / 8 = [-8 ± 4] / 8.

Correct Answer: B — x = -3/2

Q. Find the value of x in the equation 4x^2 - 16x + 15 = 0.

A. 1
B. 3
C. 5
D. 4

Solution

Factoring gives (4x - 3)(x - 5) = 0, so x = 3 or x = 5.

Correct Answer: B — 3

Q. Find the value of x in the equation 5x - 2 = 3x + 6.

A. x = 2
B. x = 3
C. x = 4
D. x = 5

Solution

Subtract 3x from both sides: 2x - 2 = 6. Add 2: 2x = 8. Divide by 2: x = 4.

Correct Answer: A — x = 2

Q. Find the value of x in the equation 5x - 2(3 - x) = 4.

A. x = 1
B. x = 2
C. x = 3

Solution

Distributing gives 5x - 6 + 2x = 4. Combining like terms: 7x - 6 = 4. Thus, 7x = 10, x = 10/7.

Correct Answer: B — x = 2

Q. Find the value of x in the equation x^2 + 6x + 9 = 0.

A. x = -3
B. x = 3
