Q1. Expand and simplify (x + 1)(x - 2)(x + 3).
A. x³ + 2x² - 5x - 6
B. x³ - 2x² - 5x - 6
C. x³ + 2x² + 5x - 6
D. x² + 2x - 6
Show answer & explanation
✓ Answer: A. x³ + 2x² - 5x - 6
First, expand two brackets: (x+1)(x-2) = x²-x-2. Then multiply by the third: (x²-x-2)(x+3) = x³+3x²-x²-3x-2x-6, which simplifies to the correct answer.
Q2. Evaluate 64^(2/3).
A. 4
B. 8
C. 16
D. 512
Show answer & explanation
✓ Answer: C. 16
The denominator of the power is the root, and the numerator is the power. So, find the cube root of 64 (which is 4) and then square the result (4² = 16).
Q3. A cuboid has dimensions 3 cm by 4 cm by 12 cm. What is the exact length of its space diagonal, connecting opposite corners?
A. 5 cm
B. 12.5 cm
C. 13 cm
D. 19 cm
Show answer & explanation
✓ Answer: C. 13 cm
The length of the space diagonal (d) in a cuboid with sides l, w, h is given by d² = l² + w² + h². So, d² = 3² + 4² + 12² = 9 + 16 + 144 = 169. Therefore, d = √169 = 13 cm.
