factor 49z^4x^2-9

factor

49 z^{4} x^{2} - 9

(7 z^{2} x + 3) (7 z^{2} x - 3)

Solution steps

49 z^{4} x^{2} - 9

49 z^{4} x^{2} = (7 z^{2} x)^{2}

9 = 3^{2}

= (7 z^{2} x)^{2} - 3^{2}

Apply Difference of Two Squares Formula:

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

(7 z^{2} x)^{2} - 3^{2} = (7 z^{2} x + 3) (7 z^{2} x - 3)

= (7 z^{2} x + 3) (7 z^{2} x - 3)

(2^{- 3} \cdot 3^{- 2})^{- 1}

22 \cdot 42

\frac{a}{b} + c

\frac{3}{5 + 3}

\frac{33}{72}
