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

expand

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

x^{4} - a^{4}

Solution steps

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

Apply Difference of Two Squares

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

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

(2 x - 4) (2 x - 4)

\frac{125}{3}

- 3 \times (- 3)

(x + 1) (x - 6)

\frac{x ^{2} - 25}{x ^{2} + 10 x + 25}
