factor 81x^2-169y^2

factor

81 x^{2} - 169 y^{2}

(9 x + 13 y) (9 x - 13 y)

Solution steps

81 x^{2} - 169 y^{2}

81 x^{2} = (9 x)^{2}

169 y^{2} = (13 y)^{2}

= (9 x)^{2} - (13 y)^{2}

Apply Difference of Two Squares Formula:

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

(9 x)^{2} - (13 y)^{2} = (9 x + 13 y) (9 x - 13 y)

= (9 x + 13 y) (9 x - 13 y)

\frac{2}{2} + 2

a^{2} + a - 380

6 x^{2} - 12 x > x^{2} + 17 x

(x - 2) (x + 4) \geq 0

\frac{x + 1}{x + 3} \geq 0
