Solution for X^2+17x+11=0 equation:



X^2+17X+11=0
a = 1; b = 17; c = +11;
Δ = b2-4ac
Δ = 172-4·1·11
Δ = 245
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{245}=\sqrt{49*5}=\sqrt{49}*\sqrt{5}=7\sqrt{5}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(17)-7\sqrt{5}}{2*1}=\frac{-17-7\sqrt{5}}{2} $
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(17)+7\sqrt{5}}{2*1}=\frac{-17+7\sqrt{5}}{2} $
