expand (8y-2y^2)^2

Solution

expand

(8 y - 2 y^{2})^{2}

Solution

64 y^{2} - 32 y^{3} + 4 y^{4}

Solution steps

(8 y - 2 y^{2})^{2}

Apply Perfect Square Formula:

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

(8 y - 2 y^{2})^{2} = (8 y)^{2} - 2 \cdot 8 y \cdot 2 y^{2} + (2 y^{2})^{2}

= (8 y)^{2} - 2 \cdot 8 y \cdot 2 y^{2} + (2 y^{2})^{2}

Simplify

(8 y)^{2} - 2 \cdot 8 y \cdot 2 y^{2} + (2 y^{2})^{2} : 64 y^{2} - 32 y^{3} + 4 y^{4}

= 64 y^{2} - 32 y^{3} + 4 y^{4}
