25x^2=174

Solution for 25x^2=174 equation:

25x^2=174

We move all terms to the left:

25x^2-(174)=0

a = 25; b = 0; c = -174;
Δ = b2-4ac
Δ = 02-4·25·(-174)
Δ = 17400
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:

$\sqrt{\Delta}=\sqrt{17400}=\sqrt{100*174}=\sqrt{100}*\sqrt{174}=10\sqrt{174}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-10\sqrt{174}}{2*25}=\frac{0-10\sqrt{174}}{50}
=-\frac{10\sqrt{174}}{50}
=-\frac{\sqrt{174}}{5}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+10\sqrt{174}}{2*25}=\frac{0+10\sqrt{174}}{50}
=\frac{10\sqrt{174}}{50}
=\frac{\sqrt{174}}{5}
