X^2+18X+82=10
We move all terms to the left:
X^2+18X+82-(10)=0
We add all the numbers together, and all the variables
X^2+18X+72=0
a = 1; b = 18; c = +72;
Δ = b2-4ac
Δ = 182-4·1·72
Δ = 36
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{36}=6$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(18)-6}{2*1}=\frac{-24}{2} =-12 $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(18)+6}{2*1}=\frac{-12}{2} =-6 $
