factor x^2+8xy-9y^2

factor

x^{2} + 8 x y - 9 y^{2}

(x - y) (x + 9 y)

Solution steps

x^{2} + 8 x y - 9 y^{2}

Break the expression into groups

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

Factor out

x

from

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

Factor out

9 y

from

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

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

Factor out common term

x - y

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

9 x^{2} - 4 x + 2 = 0

\frac{x}{2} \geq \frac{8}{x + 1} + 7

- 5.5 - 3 y - 6.7 - y = - 3 y + 8.1

6 x - 11 = 5 x + 4

4 x^{2} - 27 x - 7 = 0
