expand (w-2)^2

Solution

expand

(w - 2)^{2}

Solution

w^{2} - 4 w + 4

Solution steps

(w - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= w^{2} - 4 w + 4
