x^2-9x-32x=-10
We move all terms to the left:
x^2-9x-32x-(-10)=0
We add all the numbers together, and all the variables
x^2-41x+10=0
a = 1; b = -41; c = +10;
Δ = b2-4ac
Δ = -412-4·1·10
Δ = 1641
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{-(-41)-\sqrt{1641}}{2*1}=\frac{41-\sqrt{1641}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-41)+\sqrt{1641}}{2*1}=\frac{41+\sqrt{1641}}{2} $
