x^2+11x=189
We move all terms to the left:
x^2+11x-(189)=0
a = 1; b = 11; c = -189;
Δ = b2-4ac
Δ = 112-4·1·(-189)
Δ = 877
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{-(11)-\sqrt{877}}{2*1}=\frac{-11-\sqrt{877}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+\sqrt{877}}{2*1}=\frac{-11+\sqrt{877}}{2} $
