4m^2-24m-32=0

Solution for 4m^2-24m-32=0 equation:

4m^2-24m-32=0

a = 4; b = -24; c = -32;
Δ = b2-4ac
Δ = -242-4·4·(-32)
Δ = 1088
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1088}=\sqrt{64*17}=\sqrt{64}*\sqrt{17}=8\sqrt{17}$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-8\sqrt{17}}{2*4}=\frac{24-8\sqrt{17}}{8}
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+8\sqrt{17}}{2*4}=\frac{24+8\sqrt{17}}{8}
