2x+x(x+7)=34
We move all terms to the left:
2x+x(x+7)-(34)=0
We multiply parentheses
x^2+2x+7x-34=0
We add all the numbers together, and all the variables
x^2+9x-34=0
a = 1; b = 9; c = -34;
Δ = b2-4ac
Δ = 92-4·1·(-34)
Δ = 217
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{217}}{2*1}=\frac{-9-\sqrt{217}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{217}}{2*1}=\frac{-9+\sqrt{217}}{2} $
