1. 14x^2 + 4 + 3x - 12x^2 - 3 + 11x
2. 3x^2 + 6 - 2x + 5x - 4x^2 + 9
3. 2x^2 + 6x - 7x + 8 - 3x^2 + 1
4. In the expression -7x - 3x^2 + 5, what is the coefficient of x?

Add or subtract.
5. (m^2 - m + 3) + (m - 1)
6. (4x^2 - 2x - 1) - (-3x^3 + 2)
7. Suppose you earned 8t - 3 dollars on Monday and 6t + 5 dollars on Tuesday. What were your total earnings? Simplify your answer.
8. f^2 * f^3
9.100^12/100^8

Answer 1

Heavens, you want me to just do a whole bunch of problems for you to save you the trouble? What problem are you having with these?

Answer 2

Number 13 is either a typo or a trick :) Too easy. What is anything divided by itself?

Answer 3

Sorry, I'm just really having trouble understanding polynomials. I've watched several videos and by now, the concept normally would've clicked, but it's really just not getting through my thick skull.
