Plug in m/4 into the equation:
[tex]8 (\frac{m}{4})^{2} - 4(\frac{m}{4})[/tex]
Solve the parentheses in the equation:
[tex]\frac{m}{4}^{2} = \frac{m}{4} \times \frac{m}{4} = \frac{m^{2}}{16}[/tex]
[tex]8 \times \frac{m^{2}}{16} = \frac{8m^{2}}{16} = \frac{m^{2}}{2} [/tex]
[tex]4 \times \frac{m}{4} = \frac{4m}{4} = m[/tex]
Your equation should now look like this:
[tex]\frac{m^{2}}{2} - m[/tex]
The answer is D.
