Which polynomial is in standard form a.2x-8x^4+16x^5 b.-16x^2-9x+12, c.15x-6x^2+3, d. -7x+9x^9-11x

B. -16x^2-9x+12. Standard form for polynomials have to have the term with the largest exponent first.

Step-by-step explanation:

To get the polynomial in standard form we look at the degree of each term

In standard form we write the degree of each term from highest to lowest

a.

Here the degree is from lowest to highest. So it is not in standard form.

b.

Here, degree is x^2  and then x. degree is from highest to lowest

So, it is in standard form

c.

The degree is not in order , so it is not in standard form

d.

The degree is not in order , so it is not in standard form

answer: i think it is (1,-2)
