0.001x^2-75x=60000

Solution for 0.001x^2-75x=60000 equation:

0.001x^2-75x=60000

We move all terms to the left:

0.001x^2-75x-(60000)=0

a = 0.001; b = -75; c = -60000;
Δ = b2-4ac
Δ = -752-4·0.001·(-60000)
Δ = 5865
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-75)-\sqrt{5865}}{2*0.001}=\frac{75-\sqrt{5865}}{0.002}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-75)+\sqrt{5865}}{2*0.001}=\frac{75+\sqrt{5865}}{0.002}
