factor 121x^2y^2-1

factor

121 x^{2} y^{2} - 1

(11 x y + 1) (11 x y - 1)

Solution steps

121 x^{2} y^{2} - 1

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

1 = 1^{2}

= (11 x y)^{2} - 1^{2}

Apply Difference of Two Squares Formula:

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

(11 x y)^{2} - 1^{2} = (11 x y + 1) (11 x y - 1)

= (11 x y + 1) (11 x y - 1)

- \frac{1}{5} \cdot 4

- 6 (- 6)

- 6 (- 4)

(4 t + 2)^{2}
