expand

(- y + 1)^{2}

Solution

y^{2} - 2 y + 1

Solution steps

(- y + 1)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= y^{2} - 2 y + 1
