factor m^2-18m+81

Solution

factor

m^{2} - 18 m + 81

Solution

(m - 9)^{2}

Solution steps

m^{2} - 18 m + 81

Rewrite in the form of

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

81 = 9^{2}

- 18 m = - 2 m \cdot 9

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

Apply Perfect Square Formula:

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

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

= (m - 9)^{2}
