1. classify - 6x^5+4x^3+3x^2+11 by degree.

-quintic

-cubic

-quartic

-quadratic

2. Write - 2x^2 (-5x^2 + 4x^3) in standard form.

-8x^5 - 20x^4

-8x^5 + 10x^4

-7x + 2x^4

-7x^5 - 10x^4

1.

The degree of this polynomial is 5, and because the prefix for 5 is "quin", the answer would be quintic.

2. - 2x^2 (-5x^2 + 4x^3)

We can use FOIL to simplify this.

10x^4 - 8x^5

Because standard form is decreasing by degree, we need to rearrange the binomial.

The answer is - 8x^5 + 10x^4
