Question

simplify algebraic expression....please!!!!
3a^3+4a-9+5a^2-10a+3

Answer 1

3a^3+5a^2-6a-6

You just look for like terms. The 5a^2 and 3a^3 do not have any other like terms so they stay the same. you can add the -9 and 3 together to get 6. The -10a and 4a add together to equal -6a. Then just put the terms in order with whatever you have left over.
