expand (8mn+7m)^2

expand

(8 mn + 7 m)^{2}

64 m^{2} n^{2} + 112 m^{2} n + 49 m^{2}

Solution steps

(8 mn + 7 m)^{2}

Apply Perfect Square Formula:

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

(8 mn + 7 m)^{2} = (8 mn)^{2} + 2 \cdot 8 mn \cdot 7 m + (7 m)^{2}

= (8 mn)^{2} + 2 \cdot 8 mn \cdot 7 m + (7 m)^{2}

Simplify

(8 mn)^{2} + 2 \cdot 8 mn \cdot 7 m + (7 m)^{2} : 64 m^{2} n^{2} + 112 m^{2} n + 49 m^{2}

= 64 m^{2} n^{2} + 112 m^{2} n + 49 m^{2}

- 5 + 5 (x + 4)

\frac{4}{2 - 3}

38 \cdot 550

(- 4 x^{2} - x + 10) - (x^{2} + 10 x)

(x + 1) (x + 3) - (x - 2)^{2}
