factor 5x^2-3x-15x+9

factor

5 x^{2} - 3 x - 15 x + 9

(5 x - 3) (x - 3)

Solution steps

5 x^{2} - 3 x - 15 x + 9

Add similar elements:

- 3 x - 15 x = - 18 x

= 5 x^{2} - 18 x + 9

Break the expression into groups

= (5 x^{2} - 3 x) + (- 15 x + 9)

Factor out

x

from

5 x^{2} - 3 x : x (5 x - 3)

Factor out

- 3

from

- 15 x + 9 : - 3 (5 x - 3)

= x (5 x - 3) - 3 (5 x - 3)

Factor out common term

5 x - 3

= (5 x - 3) (x - 3)

- 8 x^{2} - 5 x - 16 = - 4 x^{2}

0 = x^{2} + 4 x + 5

\frac{11 e ^{9}}{22 e ^{10}}

5 x^{2} - 16 x + 3

x^{2} + 18 x + 32
