8m^2-104m+336=0

Solution for 8m^2-104m+336=0 equation:

8m^2-104m+336=0

a = 8; b = -104; c = +336;
Δ = b2-4ac
Δ = -1042-4·8·336
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-104)-8}{2*8}=\frac{96}{16}
=6
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-104)+8}{2*8}=\frac{112}{16}
=7
