factor 4x^3+12x^2-x-3

factor

4 x^{3} + 12 x^{2} - x - 3

(x + 3) (2 x + 1) (2 x - 1)

Solution steps

4 x^{3} + 12 x^{2} - x - 3

= (4 x^{3} + 12 x^{2}) + (- x - 3)

Factor out

4 x^{2}

from

4 x^{3} + 12 x^{2} : 4 x^{2} (x + 3)

Factor out

- 1

from

- x - 3 : - (x + 3)

= 4 x^{2} (x + 3) - (x + 3)

Factor out common term

(x + 3) : (x + 3) (4 x^{2} - 1)

= (x + 3) (4 x^{2} - 1)

Factor

4 x^{2} - 1 : (2 x + 1) (2 x - 1)

= (x + 3) (2 x + 1) (2 x - 1)

- 1 \cdot \frac{1}{3}

\frac{2}{5} \cdot 6

9 n^{2} - 27 n + 20

(2 x - 5)^{2} = 8
