simplify (3-sqrt(y))^2

Solution

simplify

(3 - y)^{2}

Solution

9 - 6 y + y

Solution steps

(3 - y)^{2}

Apply Perfect Square Formula:

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

(3 - y)^{2} = 3^{2} - 2 \cdot 3 y + (y)^{2}

= 3^{2} - 2 \cdot 3 y + (y)^{2}

3^{2} = 9

- 2 \cdot 3 y = - 6 y

(y)^{2} = y

= 9 - 6 y + y
