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}

x^{4} + 2 x^{3} - 3 x^{2}

(2 x - 5) \cdot (3 x + 4)

\frac{1}{7} \div \frac{2}{5}

(5 ab) (- 3 a^{2} b) (2 a^{3} b c)

8 (4 - 236) + 7 (\frac{3 - 2}{2})^{2}
