Question

If 4x² – 6x – m is divisible by x – 3, the value of m is exact divisor of ______.

Options

• 9

• 45

• 20

• 36

Answer 1

If 4x² – 6x – m is divisible by x – 3, the value of m is exact divisor of 9.

Explanation:

Here p(3) = 0

⇒ 4(3)² – 6 × 3 - m = 0

⇒ 36 – 18 – m = 0

⇒ m = 18

∴ Value of m is exactly divisible by 9.
