Answer 4

the highest exponent

Answer 5

of a polynomial?

Answer 6

of a polynomial in the equation?

Answer 7

yes polynomial=0
the degree of the polynomial is the highest exponent that can be found in that polynomial

Answer 8

Ok , so when x^3 -1 = 8 it is a cubic ?
But what if, x^3 + x + constant = 0? it is still cubic?

Answer 9

yep yep

Answer 10

so the highest exponent is considered. no matter how many other variables are there in the equation?

Answer 11

yep yep

Answer 12

of course we are talking about polynomials=0 right?

Answer 13
