Find the factor of polynomial P(x) = x^2+x-2

Step 1
Given
${\displaystyle P\left(x\right)=x^2+x-2}$
The given equation looks like quadratic polynomial equation.
Factorization of quadratic polynomial equation:
${\displaystyle x^2+x-2=0}$
${\displaystyle x^2+2x-1x-2=0}$ (1x = 2x-1x)
$x(x+2)-1(x+2)=0$ (take "x" common from first two terms and "-1" common from last two terms)
$(x+2)(x-1)=0$ (take "x+2" common)
Step 2
factors of given polynomial ${\displaystyle x^2+x-2=0}$
${\displaystyle x^2+x-2=(x+2)(x-1)}$
And x=-2 or x = 1.
