Question

Solve - x power 2 +x - 2 =0​

Answer 1

Answer:

Given:

$x^2 + x - 2 =0$

Solution:

$x^2 + x - 2 = 0$

$\implies x^2 +2x - x - 2 = 0$

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

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

$\boxed{\implies{\boxed{x = - 2\ or \ x = 1}}}$

Answer 2

Step-by-step explanation:

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

EXPAND THE EQUATION

WE GET

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

NOW TAKING COMMON

WE GET

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

Now Again Taking Common

WE GET

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

THEREFORE THE ANSWER IS

(X+2)(X-1)

x+2=0

x=-2

(or)

x-1=0

x=1
