factor 9a^4-x^4

factor

9 a^{4} - x^{4}

(3 a^{2} + x^{2}) (3 a^{2} - x^{2})

Solution steps

9 a^{4} - x^{4}

9 a^{4} = (3 a^{2})^{2}

x^{4} = (x^{2})^{2}

= (3 a^{2})^{2} - (x^{2})^{2}

Apply Difference of Two Squares Formula:

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

(3 a^{2})^{2} - (x^{2})^{2} = (3 a^{2} + x^{2}) (3 a^{2} - x^{2})

= (3 a^{2} + x^{2}) (3 a^{2} - x^{2})

\frac{sin ^{2} ( 2 x )}{sin ^{2} ( x )}

x (x^{\frac{1}{2}} - x)^{- 2}

a^{4} b^{4} - 16

(5 + x) 2

a^{2} \cdot b^{2} - a^{2} - b^{2} + 1
