expand (y-5)^2

Solution

expand

(y - 5)^{2}

Solution

y^{2} - 10 y + 25

Solution steps

(y - 5)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

y^{2} - 2 y \cdot 5 + 5^{2} : y^{2} - 10 y + 25

= y^{2} - 10 y + 25
