factor n^3+5n^2-9n-45

factor

n^{3} + 5 n^{2} - 9 n - 45

(n + 5) (n + 3) (n - 3)

Solution steps

n^{3} + 5 n^{2} - 9 n - 45

= (n^{3} + 5 n^{2}) + (- 9 n - 45)

Factor out

n^{2}

from

n^{3} + 5 n^{2} : n^{2} (n + 5)

Factor out

- 9

from

- 9 n - 45 : - 9 (n + 5)

= n^{2} (n + 5) - 9 (n + 5)

Factor out common term

n + 5

= (n + 5) (n^{2} - 9)

Factor

n^{2} - 9 : (n + 3) (n - 3)

= (n + 5) (n + 3) (n - 3)

1 + 6 x + 9 = 2 (3 x + 3) - x

4 t^{2} + 11 t + 2 = 0

g (- 4) = 3 (- 4)^{3} + 5

2 x + \frac{x}{y}

\frac{7}{12 x} - \frac{y}{6 x ^{2}}
