expand (2y-3)^2

Solution

expand

(2 y - 3)^{2}

Solution

4 y^{2} - 12 y + 9

Solution steps

(2 y - 3)^{2}

Apply Perfect Square Formula:

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

(2 y - 3)^{2} = (2 y)^{2} - 2 \cdot 2 y \cdot 3 + 3^{2}

= (2 y)^{2} - 2 \cdot 2 y \cdot 3 + 3^{2}

Simplify

(2 y)^{2} - 2 \cdot 2 y \cdot 3 + 3^{2} : 4 y^{2} - 12 y + 9

= 4 y^{2} - 12 y + 9
