expand (x-4y)^2

Solution

expand

(x - 4 y)^{2}

Solution

x^{2} - 8 x y + 16 y^{2}

Solution steps

(x - 4 y)^{2}

Apply Perfect Square Formula:

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

(x - 4 y)^{2} = x^{2} - 2 x \cdot 4 y + (4 y)^{2}

= x^{2} - 2 x \cdot 4 y + (4 y)^{2}

Simplify

x^{2} - 2 x \cdot 4 y + (4 y)^{2} : x^{2} - 8 x y + 16 y^{2}

= x^{2} - 8 x y + 16 y^{2}
