Like terms in the expression $n (n + 1) + 6 (n - 1)$ are _ and ___

Open in App

Solution

We have, $n (n + 1) + 6 (n - 1) = n^{2} + n + 6 n - 6$
Hence, like terms in the expression $n (n + 1) + 6 (n - 1)$ are $n$ and $6 n$

Fill in the blanks to make the statement true.

Like terms in the expression n(n+1) + 6(n-1) are ___ and ___.

n

n^{n + 1} - n {(n - 1)}^{n + 1} + \frac{n (n - 1)}{2!} {(n - 2)}^{n + 1} - \dots = \frac{1}{2} n (n + 1)!

n^{n} - (n + 1) {(n - 1)}^{n} + \frac{(n + 1) n}{2!} {(n - 2)}^{n} - \dots = 1

n

1^{n} - n 2^{n} + \frac{n (n - 1)}{1 \cdot 2} 3^{n} - \dots = {(- 1)}^{n} n!

{(n + p)}^{n} - n {(n + p - 1)}^{n} + \frac{n (n - 1)}{2!} {(n + p - 2)}^{n} - \dots = n!

n + 1

n

3 + 8 + 22 + 72 + 266 + 1036 + \dots
