expand (3c-2y)^2

Solution

expand

(3 c - 2 y)^{2}

Solution

9 c^{2} - 12 cy + 4 y^{2}

Solution steps

(3 c - 2 y)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

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