expand (8x+5y)^2

Solution

expand

(8 x + 5 y)^{2}

Solution

64 x^{2} + 80 x y + 25 y^{2}

Solution steps

(8 x + 5 y)^{2}

Apply Perfect Square Formula:

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

(8 x + 5 y)^{2} = (8 x)^{2} + 2 \cdot 8 x \cdot 5 y + (5 y)^{2}

= (8 x)^{2} + 2 \cdot 8 x \cdot 5 y + (5 y)^{2}

Simplify

(8 x)^{2} + 2 \cdot 8 x \cdot 5 y + (5 y)^{2} : 64 x^{2} + 80 x y + 25 y^{2}

= 64 x^{2} + 80 x y + 25 y^{2}
