expand (x^2-a^2)^2

Solution

expand

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

Solution

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

Solution steps

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

Apply Perfect Square Formula:

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

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

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

Simplify

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

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