factor x^2-7xy-18y^2

factor

x^{2} - 7 x y - 18 y^{2}

(x + 2 y) (x - 9 y)

Solution steps

x^{2} - 7 x y - 18 y^{2}

Break the expression into groups

= (x^{2} + 2 x y) + (- 9 x y - 18 y^{2})

Factor out

x

from

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

Factor out

- 9 y

from

- 9 x y - 18 y^{2} : - 9 y (x + 2 y)

= x (x + 2 y) - 9 y (x + 2 y)

Factor out common term

x + 2 y

= (x + 2 y) (x - 9 y)

5 = 4 - ∣ h + 3 ∣

2 x + 320 = 8 (x - 8)

x^{2} - 2 x = 9

4 x - 12 = 20
