4x^2+15x=160
We move all terms to the left:
4x^2+15x-(160)=0
a = 4; b = 15; c = -160;
Δ = b2-4ac
Δ = 152-4·4·(-160)
Δ = 2785
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{-(15)-\sqrt{2785}}{2*4}=\frac{-15-\sqrt{2785}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+\sqrt{2785}}{2*4}=\frac{-15+\sqrt{2785}}{8} $
