expand (3-y^2)^2

Solution

expand

(3 - y^{2})^{2}

Solution

9 - 6 y^{2} + y^{4}

Solution steps

(3 - y^{2})^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

3^{2} - 2 \cdot 3 y^{2} + (y^{2})^{2} : 9 - 6 y^{2} + y^{4}

= 9 - 6 y^{2} + y^{4}
