factor 80n^3+30n^2-56n-21

factor

80 n^{3} + 30 n^{2} - 56 n - 21

(8 n + 3) (10 n^{2} - 7)

Solution steps

80 n^{3} + 30 n^{2} - 56 n - 21

= (80 n^{3} + 30 n^{2}) + (- 56 n - 21)

Factor out

10 n^{2}

from

80 n^{3} + 30 n^{2} : 10 n^{2} (8 n + 3)

Factor out

- 7

from

- 56 n - 21 : - 7 (8 n + 3)

= 10 n^{2} (8 n + 3) - 7 (8 n + 3)

Factor out common term

8 n + 3

= (8 n + 3) (10 n^{2} - 7)

\frac{2}{x + 1} + \frac{1}{x + 2}

(6 x^{2} - 4 x - 5) - (3 x^{2} - 7 x + 2)

8 (2 x - 3) - 6 x

8 x^{3} + 64 y^{9}

9 a^{3} b^{2} + 12 a^{4} b
