factor 4x^2+xy-18y^2

factor

4 x^{2} + x y - 18 y^{2}

(x - 2 y) (4 x + 9 y)

Solution steps

4 x^{2} + x y - 18 y^{2}

Break the expression into groups

= (4 x^{2} - 8 x y) + (9 x y - 18 y^{2})

Factor out

4 x

from

4 x^{2} - 8 x y : 4 x (x - 2 y)

Factor out

9 y

from

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

= 4 x (x - 2 y) + 9 y (x - 2 y)

Factor out common term

x - 2 y

= (x - 2 y) (4 x + 9 y)

x^{2} + 8 x - 36 = 0

20 + 17 v = - 6 + 15 v

2 (x + 1) + 2 x = 4 x + 2

25 p^{2} + 30 p + 9

6 x = - 18
