17-x(x-3)=-66
We move all terms to the left:
17-x(x-3)-(-66)=0
We add all the numbers together, and all the variables
-x(x-3)+83=0
We multiply parentheses
-x^2+3x+83=0
We add all the numbers together, and all the variables
-1x^2+3x+83=0
a = -1; b = 3; c = +83;
Δ = b2-4ac
Δ = 32-4·(-1)·83
Δ = 341
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{-(3)-\sqrt{341}}{2*-1}=\frac{-3-\sqrt{341}}{-2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{341}}{2*-1}=\frac{-3+\sqrt{341}}{-2} $
