X^2+10-60=y

Solution for X^2+10-60=y equation:

X^2+10-60=X

We move all terms to the left:

X^2+10-60-(X)=0

We add all the numbers together, and all the variables

X^2-1X-50=0

a = 1; b = -1; c = -50;
Δ = b2-4ac
Δ = -12-4·1·(-50)
Δ = 201
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-\sqrt{201}}{2*1}=\frac{1-\sqrt{201}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{201}}{2*1}=\frac{1+\sqrt{201}}{2}
