expand (a^2-b^2)^2

Solution

expand

(a^{2} - b^{2})^{2}

Solution

a^{4} - 2 a^{2} b^{2} + b^{4}

Solution steps

(a^{2} - b^{2})^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(a^{2})^{2} - 2 a^{2} b^{2} + (b^{2})^{2} : a^{4} - 2 a^{2} b^{2} + b^{4}

= a^{4} - 2 a^{2} b^{2} + b^{4}
