148+96x-16x^2=0

Solution for 148+96x-16x^2=0 equation:

148+96x-16x^2=0

a = -16; b = 96; c = +148;
Δ = b2-4ac
Δ = 962-4·(-16)·148
Δ = 18688
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:

$\sqrt{\Delta}=\sqrt{18688}=\sqrt{256*73}=\sqrt{256}*\sqrt{73}=16\sqrt{73}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(96)-16\sqrt{73}}{2*-16}=\frac{-96-16\sqrt{73}}{-32}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(96)+16\sqrt{73}}{2*-16}=\frac{-96+16\sqrt{73}}{-32}
