Answer 2

EXPLANATION.

(x - 3) is a factor of x² + x - 12.

As we know that,

(x - 3) is a factor of the quadratic equation it means it their zeroes satisfy the equation.

⇒ x - 3 = 0.

⇒ x = 3.

Put the value of x = 3 in the equation, we get.

⇒ x² + x - 12.

⇒ (3)² + 3 - 12.

⇒ 9 + 3 - 12.

⇒ 12 - 12.

⇒ 0.

∴ The other factor of equation x² + x - 12 is 0.
