Question

2.
Remove the brackets and simplify
a) (x + 1) + (x + 2)?​

Answer 1

Step-by-step explanation:

✲ $\text{(x + 1) + (x + 2)}$

Remove the unnecessary brackets :

⇢ $\text{x + 1 + x + 2}$

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⇢ $\text{x + x + 1 + 2}$

⇢ $\text{2x + 3}$

$\red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{2x + 3}}}}}}}$
