Which polynomials are in standard form?

choose all answers that apply:

(choice a)

3z-1

(choice b)

2+4x-5x^2

(choice c)

-5p^5+2p^2-3p+1

(choice d)

none of the above

3z - 1

Step-by-step explanation:

In a standard form of a polynomial, the value in the power of the variable reduces from left to right.

Therefore, 3z - 1 polynomial is in standard form since the z term comes to the left of the constant term.

Again, polynomial is also in standard form since the power of p reduces from left to right. (Answer)
