factor n^2-13n+42

factor

n^{2} - 13 n + 42

(n - 6) (n - 7)

Solution steps

n^{2} - 13 n + 42

Break the expression into groups

= (n^{2} - 6 n) + (- 7 n + 42)

Factor out

n

from

n^{2} - 6 n : n (n - 6)

Factor out

- 7

from

- 7 n + 42 : - 7 (n - 6)

= n (n - 6) - 7 (n - 6)

Factor out common term

n - 6

= (n - 6) (n - 7)

7 x + 3 = 8 x + 1

\frac{x + 1}{3 x + 5} \leq 1

(2 + 3 i)^{2} - (3 i - 6) = 1 + 9 i

x^{3} + 7 x^{2} - 2 x - 14

6 x^{2} - 7 x - 49 = 0
