Question

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

Answer 1

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
