Question

If x-1 is one factor of the polynomial 2x Square - x -1 . Then find the others​

Answer 1

Answer :

• 2x + 1

Explanation :

Given polynomial,

⇒ 2x² - x - 1

Where one factor given is (x - 1)

Find the other.

Splitting the middle term of,

⇒ 2x² - x - 1

⇒ 2x² - 2x + x - 1

⇒ 2x(x - 1) + 1(x - 1)

⇒ (x - 1)(2x + 1) [ Taking common]

Here, one factor is given i.e., (x - 1). Hence, the other factor would be (2x + 1)

Required answer : (2x + 1)
