factor 121m^2-49n^2

factor

121 m^{2} - 49 n^{2}

(11 m + 7 n) (11 m - 7 n)

Solution steps

121 m^{2} - 49 n^{2}

121 m^{2} = (11 m)^{2}

49 n^{2} = (7 n)^{2}

= (11 m)^{2} - (7 n)^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(11 m)^{2} - (7 n)^{2} = (11 m + 7 n) (11 m - 7 n)

= (11 m + 7 n) (11 m - 7 n)

\frac{e ^{5} x ( x ^{2} + 5 ) ^{- 3}}{2}

\frac{e ^{- t}}{( e ^{- t} ) ^{\frac{1}{2}}}

- 18 a^{3} - 24 a^{2}

(- 2 x^{6} y^{- 4})^{5}

\frac{x ^{2} - 2}{3 ( - 2 x )}
