Solution for 9x^2-68x+96=0 equation:



9x^2-68x+96=0
a = 9; b = -68; c = +96;
Δ = b2-4ac
Δ = -682-4·9·96
Δ = 1168
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{1168}=\sqrt{16*73}=\sqrt{16}*\sqrt{73}=4\sqrt{73}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-68)-4\sqrt{73}}{2*9}=\frac{68-4\sqrt{73}}{18} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-68)+4\sqrt{73}}{2*9}=\frac{68+4\sqrt{73}}{18} $
