75b2=3

Solution for 75b2=3 equation:

75b^2=3

We move all terms to the left:

75b^2-(3)=0

a = 75; b = 0; c = -3;
Δ = b2-4ac
Δ = 02-4·75·(-3)
Δ = 900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{900}=30$
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-30}{2*75}=\frac{-30}{150}
=-1/5
$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+30}{2*75}=\frac{30}{150}
=1/5
