Question

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

Answer 1

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$a^{2}$ 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

Answer 2

(8a^2 + 6a + 5) + (-3a^2 -2a)

5a^2 + 4a + 5 <------------ answer
