X^2+15X+8X=0
We add all the numbers together, and all the variables
X^2+23X=0
a = 1; b = 23; c = 0;
Δ = b2-4ac
Δ = 232-4·1·0
Δ = 529
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{529}=23$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(23)-23}{2*1}=\frac{-46}{2} =-23 $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(23)+23}{2*1}=\frac{0}{2} =0 $
