-x^2+x+17=0
We add all the numbers together, and all the variables
-1x^2+x+17=0
a = -1; b = 1; c = +17;
Δ = b2-4ac
Δ = 12-4·(-1)·17
Δ = 69
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{-(1)-\sqrt{69}}{2*-1}=\frac{-1-\sqrt{69}}{-2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{69}}{2*-1}=\frac{-1+\sqrt{69}}{-2} $
