Sample question 1
What is the factored form of a2 − b2?
- (a − b)(a2 + ab + b2)
- (a + b)(a − b)
- (a + b)2
- (a − b)2
Answer: B. The difference of two squares factorizes as a2 − b2 = (a + b)(a − b).
Sample question 2
What does it mean that 5x and 3xy are factors of 15x2y?
- Their sum is 15x2y
- They are equal to each other
- Their product is 15x2y
- One of them divides the other
Answer: C. 5x × 3xy = 15x2y, so they are factors of it.
Sample question 3
Factorize x3 + 27.
- (x − 3)(x2 + 3x + 9)
- (x + 3)(x2 + 3x + 9)
- (x + 3)3
- (x + 3)(x2 − 3x + 9)
Answer: D. x3 + 27 = x3 + 33 = (x + 3)(x2 − 3x + 9).
