2x^2+44x=640
We move all terms to the left:
2x^2+44x-(640)=0
a = 2; b = 44; c = -640;
Δ = b2-4ac
Δ = 442-4·2·(-640)
Δ = 7056
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{7056}=84$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(44)-84}{2*2}=\frac{-128}{4} =-32 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(44)+84}{2*2}=\frac{40}{4} =10 $
