(x+3)(x)=775
We move all terms to the left:
(x+3)(x)-(775)=0
We multiply parentheses
x^2+3x-775=0
a = 1; b = 3; c = -775;
Δ = b2-4ac
Δ = 32-4·1·(-775)
Δ = 3109
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{-(3)-\sqrt{3109}}{2*1}=\frac{-3-\sqrt{3109}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{3109}}{2*1}=\frac{-3+\sqrt{3109}}{2} $
