Question

solve the equation x^2+x-2​

Answer 1

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

Answer 2

Answer:

x. = 1. & x. = -2

Step-by-step explanation:

x2+x-2=0

x(x+2) -1(x+2)

(x-1). &. (x+2)

THEREFORE: X. = 1. & X. = -2
