factor x^2+2xy-99y^2

factor

x^{2} + 2 x y - 99 y^{2}

(x - 9 y) (x + 11 y)

Solution steps

x^{2} + 2 x y - 99 y^{2}

Break the expression into groups

= (x^{2} - 9 x y) + (11 x y - 99 y^{2})

Factor out

x

from

x^{2} - 9 x y : x (x - 9 y)

Factor out

11 y

from

11 x y - 99 y^{2} : 11 y (x - 9 y)

= x (x - 9 y) + 11 y (x - 9 y)

Factor out common term

x - 9 y

= (x - 9 y) (x + 11 y)

(a + b)^{2}

\frac{4}{4}

- 20 > - 2 x + 4

5 - \frac{2}{x} < 1

\frac{1}{- 5. 5 ^{2} - 25}
