simplify (1-sqrt(y))^2

Solution

simplify

(1 - y)^{2}

Solution

1 - 2 y + y

Solution steps

(1 - y)^{2}

Apply Perfect Square Formula:

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

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

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

1^{2} = 1

- 2 \cdot 1 \cdot y = - 2 y

(y)^{2} = y

= 1 - 2 y + y
