n2 + 11n + 18 = n2 + 2n + 9n + 18 = n(n+2) + 9(n+2) = (n+9)*(n+2)
n2 - 11n - 26what two factors of - 26 add up to - 11?(n + 2)(n - 13)===========
Assuming you mean n2 + 11n + 30, the factors are (n + 6)(n + 5).
F.O.I.L First, outer, inner, and last. (n - 1) (n - 10)
n2 + 9n + 18 = (n + 6)(n + 3)
n2 + 11n + 18 = n2 + 2n + 9n + 18 = n(n+2) + 9(n+2) = (n+9)*(n+2)
If that's -11n, the answer is (n - 14)(n + 3) If that's +11n, the answer is (n + 14)(n - 3)
n2 - 11n - 26what two factors of - 26 add up to - 11?(n + 2)(n - 13)===========
Assuming you mean n2 + 11n + 30, the factors are (n + 6)(n + 5).
F.O.I.L First, outer, inner, and last. (n - 1) (n - 10)
n2 + 9n + 18 = (n + 6)(n + 3)
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
11n - 12n + 3 = 3 - n
The GCF is n.
In most cases: 11n is ultra light, neutral blonde.
This can not be solved as it is not an equation but a simple expression. If you are looking to factor it, then the answer is: n2 - 3n - 18 = (n - 6)(n + 3)
3m + 11n = 3
