-------------------------------------------------------------
(A)
Remove parentheses:
3a^2+1 - 4+2a^2
Simplify:
3a^2+1 - 4+2a^2
Group like terms:
3a^2-2a^2+1-4
Add similar elements:
a^2++1-4
Add/ subtract the numbers:
a^2-3
Your Answer For Equation (A) Is a^2-3
----------------------------------------------------------
(B)
Remove parentheses:
5p^2-3 + 2p^2-3p^3
Group like terms:
-3p^3+5p^2+2p^2-3

9r^3+5r^2+11r + -2r^3+9r-8r^2
Group like terms:
9r^3-2r^3+5r^2-8r^2+11r+9r
Add similar elements:
9r^3-2r^3-3r^2+11r+9r
7r^3-3r^2+11r+9r
7r^3-3r^2+20r
Your Answer For Equation (D) Is 7r^3-3r^2+20r
