2x^2+20x-528=0
a = 2; b = 20; c = -528;
Δ = b2-4ac
Δ = 202-4·2·(-528)
Δ = 4624
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{4624}=68$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(20)-68}{2*2}=\frac{-88}{4} =-22 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(20)+68}{2*2}=\frac{48}{4} =12 $
