(17+x)(18+x)=0
We add all the numbers together, and all the variables
(x+17)(x+18)=0
We multiply parentheses ..
(+x^2+18x+17x+306)=0
We get rid of parentheses
x^2+18x+17x+306=0
We add all the numbers together, and all the variables
x^2+35x+306=0
a = 1; b = 35; c = +306;
Δ = b2-4ac
Δ = 352-4·1·306
Δ = 1
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{1}=1$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(35)-1}{2*1}=\frac{-36}{2} =-18 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(35)+1}{2*1}=\frac{-34}{2} =-17 $
