Solution

9 m^{2} + 6 m + 1

Solution steps

(3 m + 1)^{2}

Apply Perfect Square Formula:

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

(3 m + 1)^{2} = (3 m)^{2} + 2 \cdot 3 m \cdot 1 + 1^{2}

= (3 m)^{2} + 2 \cdot 3 m \cdot 1 + 1^{2}

Simplify

(3 m)^{2} + 2 \cdot 3 m \cdot 1 + 1^{2} : 9 m^{2} + 6 m + 1

= 9 m^{2} + 6 m + 1
