expand (2m+1)^2

Solution

expand

(2 m + 1)^{2}

Solution

4 m^{2} + 4 m + 1

Solution steps

(2 m + 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(2 m)^{2} + 2 \cdot 2 m \cdot 1 + 1^{2} : 4 m^{2} + 4 m + 1

= 4 m^{2} + 4 m + 1
