expand (v-4)^2

Solution

expand

(v - 4)^{2}

Solution

v^{2} - 8 v + 16

Solution steps

(v - 4)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= v^{2} - 8 v + 16
