Question

x² + x -2 = 0 find the value of X​

Answer 1

Answer:

x = (-2). or. x = 1.

Step-by-step explanation:

${x}^{2} + x - 2 = 0$

(NOW, BY FACTORISATION METHOD)

${x}^{2} + 2x - x - 2 = 0$ = 0.

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

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

EITHER,,

x+2 = 0. x-1 = 0.

: x = (-2). ; x = 1.

Answer 2

Step-by-step explanation:

$x² + x -2 = 0 \: find \: the \: value \: of \: X.$

$\implies \: x² + x -2 = 0$

$\implies \: {x}^{2} + x - 2x - 2 = 0$

$\implies \: x(x + 1) - 2(x + 1) = 0$

$\implies \: (x + 1)(x - 2) = 0$

$\implies \: x + 1 = 0 \: or \: x - 2 = 0$

$\implies \: x = - 1 \: or \: x = 2$

$So, \: x \: = - 1, 2$
