expand (2y+1)^2

Solution

expand

(2 y + 1)^{2}

Solution

4 y^{2} + 4 y + 1

Solution steps

(2 y + 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

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