expand (5m+2n)^2

Solution

expand

(5 m + 2 n)^{2}

Solution

25 m^{2} + 20 mn + 4 n^{2}

Solution steps

(5 m + 2 n)^{2}

Apply Perfect Square Formula:

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

(5 m + 2 n)^{2} = (5 m)^{2} + 2 \cdot 5 m \cdot 2 n + (2 n)^{2}

= (5 m)^{2} + 2 \cdot 5 m \cdot 2 n + (2 n)^{2}

Simplify

(5 m)^{2} + 2 \cdot 5 m \cdot 2 n + (2 n)^{2} : 25 m^{2} + 20 mn + 4 n^{2}

= 25 m^{2} + 20 mn + 4 n^{2}
