factor 81x^2-100y^2

factor

81 x^{2} - 100 y^{2}

(9 x + 10 y) (9 x - 10 y)

Solution steps

81 x^{2} - 100 y^{2}

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

100 y^{2} = (10 y)^{2}

= (9 x)^{2} - (10 y)^{2}

Apply Difference of Two Squares Formula:

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

(9 x)^{2} - (10 y)^{2} = (9 x + 10 y) (9 x - 10 y)

= (9 x + 10 y) (9 x - 10 y)

77 = 11 \cdot h

(x - \frac{1}{2}) (2 x^{2} - 2 x - 12) \geq 0

\frac{- 8 n + 4}{11 n ( n + 1 )} \cdot \frac{4 n ^{2}}{- 10 n + 5}

9 w^{2} + 9 w - 4

(- \frac{5}{6})^{2}
