74w^2+48w=0
a = 74; b = 48; c = 0;
Δ = b2-4ac
Δ = 482-4·74·0
Δ = 2304
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{2304}=48$$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(48)-48}{2*74}=\frac{-96}{148} =-24/37 $$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(48)+48}{2*74}=\frac{0}{148} =0 $
