factor 169x^2-121y^2

factor

169 x^{2} - 121 y^{2}

(13 x + 11 y) (13 x - 11 y)

Solution steps

169 x^{2} - 121 y^{2}

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

121 y^{2} = (11 y)^{2}

= (13 x)^{2} - (11 y)^{2}

Apply Difference of Two Squares Formula:

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

(13 x)^{2} - (11 y)^{2} = (13 x + 11 y) (13 x - 11 y)

= (13 x + 11 y) (13 x - 11 y)

n^{2} - 7 n - 18

\frac{1}{4} \cdot \frac{1}{4} \cdot \frac{1}{4}

- x^{2} + 4 x < 4

\frac{5}{12 x ^{4} y} - \frac{1}{5 x ^{2} y ^{3}}

9 x^{2} = 16
