x^2=7165

Solution for x^2=7165 equation:

x^2=7165

We move all terms to the left:

x^2-(7165)=0

a = 1; b = 0; c = -7165;
Δ = b2-4ac
Δ = 02-4·1·(-7165)
Δ = 28660
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:

$\sqrt{\Delta}=\sqrt{28660}=\sqrt{4*7165}=\sqrt{4}*\sqrt{7165}=2\sqrt{7165}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{7165}}{2*1}=\frac{0-2\sqrt{7165}}{2}
=-\frac{2\sqrt{7165}}{2}
=-\sqrt{7165}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{7165}}{2*1}=\frac{0+2\sqrt{7165}}{2}
=\frac{2\sqrt{7165}}{2}
=\sqrt{7165}
