factor 9x^3+9x^2y-x-y

factor

9 x^{3} + 9 x^{2} y - x - y

(x + y) (3 x + 1) (3 x - 1)

Solution steps

9 x^{3} + 9 x^{2} y - x - y

= (9 x^{3} + 9 x^{2} y) + (- x - y)

Factor out

9 x^{2}

from

9 x^{3} + 9 x^{2} y : 9 x^{2} (x + y)

Factor out

- 1

from

- x - y : - (x + y)

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

Factor out common term

(x + y) : (x + y) (9 x^{2} - 1)

= (x + y) (9 x^{2} - 1)

Factor

9 x^{2} - 1 : (3 x + 1) (3 x - 1)

= (x + y) (3 x + 1) (3 x - 1)

x^{2} - 12 x + 16 = 0

\frac{5}{5 + 6 i}

\frac{4 a ^{2} - 20 a + 25}{25 - 4 a ^{2}}

\frac{14}{4}

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