97=215x+16x^2
We move all terms to the left:
97-(215x+16x^2)=0
We get rid of parentheses
-16x^2-215x+97=0
a = -16; b = -215; c = +97;
Δ = b2-4ac
Δ = -2152-4·(-16)·97
Δ = 52433
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{-(-215)-\sqrt{52433}}{2*-16}=\frac{215-\sqrt{52433}}{-32} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-215)+\sqrt{52433}}{2*-16}=\frac{215+\sqrt{52433}}{-32} $
