Answer:

a. 6x^2+x+0.7

b. 5x^2-2x-2

Step-by-step explanation:

a. 6x^2+2x-3-x+4.7-1

Simplest form is when all the terms are ordered by power and like terms are combined. I'm assuming the first term is 6x^2 because 6x2 seems a bit odd to me. When you combine like terms and reorder everything, you get

6x^2+x+0.7

b. 6x^2+2x-3-x^2-4x+1

The first thing I did was distribute the negative. Next, you just repeat the same steps. Combine like terms and reorder. The final result is:

5x^2-2x-2
