expand (5n-2m)*(5n+2m)

expand

(5 n - 2 m) \cdot (5 n + 2 m)

25 n^{2} - 4 m^{2}

Solution steps

(5 n - 2 m) (5 n + 2 m)

Apply Difference of Two Squares

(5 n - 2 m) (5 n + 2 m) : 25 n^{2} - 4 m^{2}

= 25 n^{2} - 4 m^{2}

\frac{1}{2} + (- 3)

\frac{6}{7} - \frac{9}{28}

(5 x^{2} + y)^{2}

\frac{5}{12} - \frac{- 16}{- 12}

\frac{2}{6} + \frac{4}{6}
