Question

Like terms in the expression $\mathrm{n}(\mathrm{n}+1)+6(\mathrm{n}–1)$ are ___________and ________.

• A. $\mathrm{n}$
• B. $6\mathrm{n}$

Answer 1

Find like terms:

Given: $\mathrm{n}(\mathrm{n}+1)+6(\mathrm{n}–1)$

Like terms:Like terms are those which contain the same variable that is the variable with the same power.

By simplifying we get ${\mathrm{n}}^2+\mathrm{n}+6\mathrm{n}-6$

Therefore like terms are $\mathrm{n}$ and $6\mathrm{n}.$

Hence,Like terms in the expression $\mathrm{n}(\mathrm{n}+1)+6(\mathrm{n}–1)$ are ____$n$_______and __$6n$___.
