Question 18
PolynomialsWhich of the following is a facor of p(x) = ax3 − bx2 + bx − a
- A.ax − b
- B.x − 1
- C.x + 1
- D.ax + b
Show the answer and explanation
Answer: B (x − 1)
Explanation
p(1) = a − b + b − a = 0, so x − 1 is a factor.
Which of the following is a facor of p(x) = ax3 − bx2 + bx − a
Answer: B (x − 1)
p(1) = a − b + b − a = 0, so x − 1 is a factor.
