Question

express the following polynomials in standard form and also write their degrees (z^3-4) (z^3-5)​

Answer 1

Step-by-step explanation:

happy new year............

Answer 2

Answer:

6

Step-by-step explanation:

(z³-4)(z³-5) = (z³)² -(4+5)z³ +(4*5)

= z^6 - 9z³ + 20

Used formula :

(x-a)(x-b) = x²-(a+b)x + ab

Degree is the highest power of the polynomial.

so , the degree of z^6 - 9z³ + 20.
