Like terms in the expression n(n + 1) + 6 (n - 1) are ___________and ________. Fill in the blanks to make the statement true.

Solution:

Given, the like terms in the expression n(n + 1) + 6(n - 1) are ______ and ______.

We have to fill in the blanks to make the statement true.

n(n + 1) = n² + n

6(n - 1) = 6n - 6

Now, n(n + 1) + 6 (n - 1) = n² + n + 6n - 6

Therefore, the like terms are n and 6n.

✦ Try This: Like terms in the expression n(n - 1) + 5 (n + 1) are ___________and ________. Fill in the blanks to make the statement true.

Given, the like terms in the expression n(n - 1) + 5 (n + 1) are ______ and ______.

We have to fill in the blanks to make the statement true.

n(n - 1) = n² - n

5(n + 1) = 5n + 5

Now, n(n - 1) + 5 (n + 1) = n² - n + 5n + 5

Therefore, the like terms are -n and 5n.
