Answer:
Option b) [tex]6j^2+3[/tex]
Step-by-step explanation:
We are given two algebraic expressions as
[tex]4j^2+6[/tex] and [tex]2j^2-3[/tex]
We have to add these two
We group like terms and simplify them
Here we get
[tex]4j^2+6+2j^2-3[/tex]
Group j square times separately and constant terms separately
[tex]4j^2+2j^2+6-3\\6j^2+3[/tex]
Thus answer is option a.
