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

Factor out

n

from

n^{2} - 5 n : n (n - 5)

Factor out

9

from

9 n - 45 : 9 (n - 5)

= n (n - 5) + 9 (n - 5)

n - 5

= (n - 5) (n + 9)

x^{2} = 11 x - 28

\frac{2 - 3 x}{1 + x} > 1

4 x^{2} - 6 x + 5 = 0

33 (- \frac{1}{2 ( 1 0 ^{2} )} + \frac{1}{2})

3 x^{2} + x - 8 = 0
