expand (5-2y)^2

Solution

expand

(5 - 2 y)^{2}

Solution

25 - 20 y + 4 y^{2}

Solution steps

(5 - 2 y)^{2}

Apply Perfect Square Formula:

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

(5 - 2 y)^{2} = 5^{2} - 2 \cdot 5 \cdot 2 y + (2 y)^{2}

= 5^{2} - 2 \cdot 5 \cdot 2 y + (2 y)^{2}

Simplify

5^{2} - 2 \cdot 5 \cdot 2 y + (2 y)^{2} : 25 - 20 y + 4 y^{2}

= 25 - 20 y + 4 y^{2}
