Simplify (2m?u)2?(m?2u)25m2?5u2

Question 1 Report

Simplify $\frac{(2 m - u)^{2} - (m - 2 u)^{2}}{5 m^{2} - 5 u^{2}}$

\frac{3}{5}

\frac{2}{5}

\frac{2 m - u}{5 m + u}

\frac{m - 2 u}{m + 5 u}

Answer Details

$\frac{(2 m - u)^{2} - (m - 2 u)^{2}}{5 m^{2} - 5 u^{2}}$
= $\frac{2 m - u + m - 2 u) (2 m - u - m + 2 u)}{5 (m + u) (m - u)}$
= $\frac{3 (m - u) (m + u)}{5 (m + u) (m - u)}$
= $\frac{3}{5}$
