Question

-x^4+5x^3+7x^2-16 find degree and coefficient

Answer 1

The degree is the highest value of the powers.
I assume you mean 'leading' coefficient for the 2nd part?
Leading coefficient is the coefficient for the term with the highest degree.
Which in this case is -x^4 (since 4 is the highest degree). The coefficient of it is the number that it multiplies by.

Basically, what multiplies by x^4 = -x^4? That will be your leading coefficient.
And which term has the highest degree value? That will be the degree of the polynomial.

Answer 2

okay so what is the answers i need it asap

Answer 3

degree is 4

Answer 4

Yes, the degree is 4. Now what times x^4 is -x^4?

I can't directly say the answer or I'll get a warning from the mods btw :P

Answer 5

-1?

Answer 6

Yep
