3x*1x=1875

Solution for 3x*1x=1875 equation:

3x*1x=1875

We move all terms to the left:

3x*1x-(1875)=0

Wy multiply elements

3x^2-1875=0

a = 3; b = 0; c = -1875;
Δ = b2-4ac
Δ = 02-4·3·(-1875)
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*3}=\frac{-150}{6}
=-25
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+150}{2*3}=\frac{150}{6}
=25
