Solution for 5x2+16x-96=0 equation:



5x^2+16x-96=0
a = 5; b = 16; c = -96;
Δ = b2-4ac
Δ = 162-4·5·(-96)
Δ = 2176
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:
$\sqrt{\Delta}=\sqrt{2176}=\sqrt{64*34}=\sqrt{64}*\sqrt{34}=8\sqrt{34}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(16)-8\sqrt{34}}{2*5}=\frac{-16-8\sqrt{34}}{10} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(16)+8\sqrt{34}}{2*5}=\frac{-16+8\sqrt{34}}{10} $
