factor-n^2-9n-8

factor

- n^{2} - 9 n - 8

- (n + 1) (n + 8)

Solution steps

- n^{2} - 9 n - 8

Break the expression into groups

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

Factor out

- n

from

- n^{2} - n : - n (n + 1)

Factor out

- 8

from

- 8 n - 8 : - 8 (n + 1)

= - n (n + 1) - 8 (n + 1)

Factor out common term

n + 1

= (n + 1) (- n - 8)

Factor

- n - 8 : - (n + 8)

= (n + 1) (- (n + 8))

Apply rule:

a (- b) = - ab

(n + 1) (- (n + 8)) = - (n + 1) (n + 8)

= - (n + 1) (n + 8)

- 6 y - 11 = y^{2}

3 x^{2} = - 8 x - 1

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

5 x + 2 < 5 (x + 1)

x^{2} - 10 x + 27 \leq 0
