Question

Find the remainder when f(x) = 2x3 − 5x2 + 8x + 4 is divided by 2x − 1, and use it to determine if 2x − 1 is a factor.

0; it is a factor
6; it is not a factor
7; it is not a factor
9.75; it is not a factor

Answer 1

Answer:

7; not a factor

Step-by-step explanation:

2x³ - x² - 4x² + 2x + 6x - 3 + 7

x²(2x-1) - 2x(2x-1) + 3(2x-1) + 7

7 is the remainder.

Hence, not a factor
