expand (1-2y)^2

Solution

expand

(1 - 2 y)^{2}

Solution

1 - 4 y + 4 y^{2}

Solution steps

(1 - 2 y)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

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