factor v^2-18v+81

Solution

factor

v^{2} - 18 v + 81

Solution

(v - 9)^{2}

Solution steps

v^{2} - 18 v + 81

Rewrite in the form of

a^{2} + 2 ab + b^{2} :

81 = 9^{2}

- 18 v = - 2 v \cdot 9

= v^{2} - 2 v \cdot 9 + 9^{2}

Apply Perfect Square Formula:

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

v^{2} - 2 v \cdot 9 + 9^{2} = (v - 9)^{2}

= (v - 9)^{2}
