factor n^2-9n+20

factor

n^{2} - 9 n + 20

(n - 4) (n - 5)

Solution steps

n^{2} - 9 n + 20

Break the expression into groups

= (n^{2} - 4 n) + (- 5 n + 20)

Factor out

n

from

n^{2} - 4 n : n (n - 4)

Factor out

- 5

from

- 5 n + 20 : - 5 (n - 4)

= n (n - 4) - 5 (n - 4)

Factor out common term

n - 4

= (n - 4) (n - 5)

8^{2} + b^{2} = 1 5^{2}

24 x^{2} = 24

- x^{3} - x^{2} + 5 x - 3

- 5.4 x + 6.7 = 7.5

12 z^{2} - 25 z + 12 \leq 0
