Find the sum and express it in simplest form (8a^2 + 6a + 5) + (-3a^2 - 2a)

What we are going to do with this problem is combine all the like terms.
so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a.

thus:
8
a^(2)+(-3
a^(2) is going to equal 5
a^(2)</strong> because adding a negative is just like subtracting.

then we move on to (6a)-(2a) giving us 4a
5 is the only term that stays the same because there are no other similar terms.
last but not least, put the equation together!

answer: 5
a^(2)+4a+5
