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)

4 \cdot (- \frac{1}{4})

(1 0^{- 2})^{3}

(2 x - 3) (x + 6)

\frac{1}{6} - \frac{5}{6}

5 x^{2} + 4 + 6 y - 1 + 3 y - 4 x^{2} - 5
