factor n^2-2n-80

factor

n^{2} - 2 n - 80

(n + 8) (n - 10)

Solution steps

n^{2} - 2 n - 80

Break the expression into groups

= (n^{2} + 8 n) + (- 10 n - 80)

Factor out

n

from

n^{2} + 8 n : n (n + 8)

Factor out

- 10

from

- 10 n - 80 : - 10 (n + 8)

= n (n + 8) - 10 (n + 8)

Factor out common term

n + 8

= (n + 8) (n - 10)

- \frac{3}{4} x \geq - \frac{5}{6} + \frac{1}{3} x

\frac{x - 1}{x + 4} > 3

2 (x - 1)^{2} = x^{2} - 1

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

\frac{7}{10} - \frac{1}{3} + 2
