expand (11m-3n)^2

Solution

expand

(11 m - 3 n)^{2}

Solution

121 m^{2} - 66 mn + 9 n^{2}

Solution steps

(11 m - 3 n)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(11 m - 3 n)^{2} = (11 m)^{2} - 2 \cdot 11 m \cdot 3 n + (3 n)^{2}

= (11 m)^{2} - 2 \cdot 11 m \cdot 3 n + (3 n)^{2}

Simplify

(11 m)^{2} - 2 \cdot 11 m \cdot 3 n + (3 n)^{2} : 121 m^{2} - 66 mn + 9 n^{2}

= 121 m^{2} - 66 mn + 9 n^{2}
