Question

Re-arrange this polynomial so it’s terms are in order from highest to lowest. 4x to the 5th power + 2x to the 3rd power - 15 - 7x to the second power

Answer 1

`4x^5+2x^3-7x^2-15`

Explanation:

Look at the degrees of each term.

`4x^5=5 \\ \\ 2x^3=3 \\ \\ -7x^2 = 2 \\ \\ -15=1`

Rearrange them from greatest to least.

`4x^5+2x^3-7x^2-15`
