6m^2+8=72
We move all terms to the left:
6m^2+8-(72)=0
We add all the numbers together, and all the variables
6m^2-64=0
a = 6; b = 0; c = -64;
Δ = b2-4ac
Δ = 02-4·6·(-64)
Δ = 1536
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}$$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{1536}=\sqrt{256*6}=\sqrt{256}*\sqrt{6}=16\sqrt{6}$$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-16\sqrt{6}}{2*6}=\frac{0-16\sqrt{6}}{12} =-\frac{16\sqrt{6}}{12} =-\frac{4\sqrt{6}}{3} $$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+16\sqrt{6}}{2*6}=\frac{0+16\sqrt{6}}{12} =\frac{16\sqrt{6}}{12} =\frac{4\sqrt{6}}{3} $
