expand (v-3)^2

Solution

expand

(v - 3)^{2}

Solution

v^{2} - 6 v + 9

Solution steps

(v - 3)^{2}

Apply Perfect Square Formula:

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

(v - 3)^{2} = v^{2} - 2 v \cdot 3 + 3^{2}

= v^{2} - 2 v \cdot 3 + 3^{2}

Simplify

v^{2} - 2 v \cdot 3 + 3^{2} : v^{2} - 6 v + 9

= v^{2} - 6 v + 9
