x2-45=4050

Solution for x2-45=4050 equation:

x2-45=4050

We move all terms to the left:

x2-45-(4050)=0

We add all the numbers together, and all the variables

x^2-4095=0

a = 1; b = 0; c = -4095;
Δ = b2-4ac
Δ = 02-4·1·(-4095)
Δ = 16380
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{16380}=\sqrt{36*455}=\sqrt{36}*\sqrt{455}=6\sqrt{455}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-6\sqrt{455}}{2*1}=\frac{0-6\sqrt{455}}{2}
=-\frac{6\sqrt{455}}{2}
=-3\sqrt{455}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+6\sqrt{455}}{2*1}=\frac{0+6\sqrt{455}}{2}
=\frac{6\sqrt{455}}{2}
=3\sqrt{455}
