An 8th degree polynomial can have up to 7 extrema (local maxima and minima). This is because the number of extrema is limited by the degree of the polynomial minus one, which in this case is (8 - 1 = 7). However, the actual number of extrema can be fewer depending on the specific polynomial and its critical points.

There is no polynomial below.(Although I'll bet there was one wherever you copied the question from.)
The discriminant is -7
If (x + 3)(x +7) = 0 then either: x + 3 = 0 or x + 7 = 7 Hence x = -3 or -7.
The degree of a polynomial is the highest degree of its terms.The degree of a term is the sum of the exponents of the variables.7x3y2 + 15xy6 + 23x2y2The degree of the first term is 5.The degree of the second term is 7.The degree of the third term is 4.The degree of the polynomial is 7.
