expand (w-4)^2

Solution

expand

(w - 4)^{2}

Solution

w^{2} - 8 w + 16

Solution steps

(w - 4)^{2}

Apply Perfect Square Formula:

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

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

= w^{2} - 2 w \cdot 4 + 4^{2}

Simplify

w^{2} - 2 w \cdot 4 + 4^{2} : w^{2} - 8 w + 16

= w^{2} - 8 w + 16
