expand (14y-7x)^2

Solution

expand

(14 y - 7 x)^{2}

Solution

196 y^{2} - 196 y x + 49 x^{2}

Solution steps

(14 y - 7 x)^{2}

Apply Perfect Square Formula:

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

(14 y - 7 x)^{2} = (14 y)^{2} - 2 \cdot 14 y \cdot 7 x + (7 x)^{2}

= (14 y)^{2} - 2 \cdot 14 y \cdot 7 x + (7 x)^{2}

Simplify

(14 y)^{2} - 2 \cdot 14 y \cdot 7 x + (7 x)^{2} : 196 y^{2} - 196 y x + 49 x^{2}

= 196 y^{2} - 196 y x + 49 x^{2}
