X2=36x

Solution for X2=36x equation:

X2=36X

We move all terms to the left:

X2-(36X)=0

We add all the numbers together, and all the variables

X^2-36X=0

a = 1; b = -36; c = 0;
Δ = b2-4ac
Δ = -362-4·1·0
Δ = 1296
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1296}=36$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-36)-36}{2*1}=\frac{0}{2}
=0
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-36)+36}{2*1}=\frac{72}{2}
=36
