X2=132-x

Solution for X2=132-x equation:

X2=132-X

We move all terms to the left:

X2-(132-X)=0

We add all the numbers together, and all the variables

X2-(-1X+132)=0

We add all the numbers together, and all the variables

X^2-(-1X+132)=0

We get rid of parentheses

X^2+1X-132=0

We add all the numbers together, and all the variables

X^2+X-132=0

a = 1; b = 1; c = -132;
Δ = b2-4ac
Δ = 12-4·1·(-132)
Δ = 529
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{529}=23$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-23}{2*1}=\frac{-24}{2}
=-12
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+23}{2*1}=\frac{22}{2}
=11
