5x*3x=375

Solution for 5x*3x=375 equation:

5x*3x=375

We move all terms to the left:

5x*3x-(375)=0

Wy multiply elements

15x^2-375=0

a = 15; b = 0; c = -375;
Δ = b2-4ac
Δ = 02-4·15·(-375)
Δ = 22500
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{22500}=150$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-150}{2*15}=\frac{-150}{30}
=-5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+150}{2*15}=\frac{150}{30}
=5
