factor 16x^2y^2-81

factor

16 x^{2} y^{2} - 81

(4 x y + 9) (4 x y - 9)

Solution steps

16 x^{2} y^{2} - 81

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

81 = 9^{2}

= (4 x y)^{2} - 9^{2}

Apply Difference of Two Squares Formula:

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

(4 x y)^{2} - 9^{2} = (4 x y + 9) (4 x y - 9)

= (4 x y + 9) (4 x y - 9)

- 7 - 28

\frac{26}{16}

\frac{26}{- 2}

e^{l n (1 - x)}

- \frac{1}{2} - \frac{7}{2}
