expand (2y+8x)^2

Solution

expand

(2 y + 8 x)^{2}

Solution

4 y^{2} + 32 y x + 64 x^{2}

Solution steps

(2 y + 8 x)^{2}

Apply Perfect Square Formula:

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

(2 y + 8 x)^{2} = (2 y)^{2} + 2 \cdot 2 y \cdot 8 x + (8 x)^{2}

= (2 y)^{2} + 2 \cdot 2 y \cdot 8 x + (8 x)^{2}

Simplify

(2 y)^{2} + 2 \cdot 2 y \cdot 8 x + (8 x)^{2} : 4 y^{2} + 32 y x + 64 x^{2}

= 4 y^{2} + 32 y x + 64 x^{2}
