5x2=375

Solution for 5x2=375 equation:

5x^2=375

We move all terms to the left:

5x^2-(375)=0

a = 5; b = 0; c = -375;
Δ = b2-4ac
Δ = 02-4·5·(-375)
Δ = 7500
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:

$\sqrt{\Delta}=\sqrt{7500}=\sqrt{2500*3}=\sqrt{2500}*\sqrt{3}=50\sqrt{3}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-50\sqrt{3}}{2*5}=\frac{0-50\sqrt{3}}{10}
=-\frac{50\sqrt{3}}{10}
=-5\sqrt{3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+50\sqrt{3}}{2*5}=\frac{0+50\sqrt{3}}{10}
=\frac{50\sqrt{3}}{10}
=5\sqrt{3}
