Question

Factorise: x² + x - 2​

Answer 1

Answer:

(x-1)(x+2)

Step-by-step explanation:

${x}^{2} + x - 2 \\ = {x}^{2} + 2x - x - 2 \\ = x(x + 2) - 1(x + 2) \\ = (x - 1)(x + 2)$

Answer 2

Step-by-step explanation:

By factorization

x^2 + x - 2 = 0

x^2 +x - 2x - 2 = 0

x (x + 1 ) -2 ( x + 1) = 0

x - 2 = 0 x + 1 = 0

x = 2 and x = -1

The factors of the equation is (x - 2) and (x + 1)

The factors of the equation is (x - 2) and (x + 1)The value of x is +2 and -1.
