expand (8x-7y)^2

Solution

expand

(8 x - 7 y)^{2}

Solution

64 x^{2} - 112 x y + 49 y^{2}

Solution steps

(8 x - 7 y)^{2}

Apply Perfect Square Formula:

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

(8 x - 7 y)^{2} = (8 x)^{2} - 2 \cdot 8 x \cdot 7 y + (7 y)^{2}

= (8 x)^{2} - 2 \cdot 8 x \cdot 7 y + (7 y)^{2}

Simplify

(8 x)^{2} - 2 \cdot 8 x \cdot 7 y + (7 y)^{2} : 64 x^{2} - 112 x y + 49 y^{2}

= 64 x^{2} - 112 x y + 49 y^{2}
