X^2+9X=209
We move all terms to the left:
X^2+9X-(209)=0
a = 1; b = 9; c = -209;
Δ = b2-4ac
Δ = 92-4·1·(-209)
Δ = 917
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{-(9)-\sqrt{917}}{2*1}=\frac{-9-\sqrt{917}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{917}}{2*1}=\frac{-9+\sqrt{917}}{2} $
