Plz urgent ​


Sagot :

Answer:

The degree of polynomial is 2

Step-by-step explanation:

Given

[tex]p(y) = (y -4)^3 - y^3[/tex]

Required

The degree

When expanded,  [tex]p(y) = (y -4)^3 - y^3[/tex] is:

[tex]p(y) =y^3-12y^2+48y-64-y^3[/tex]

Collect like terms

[tex]p(y) =-12y^2+48y-64-y^3+y^3[/tex]

[tex]p(y) =-12y^2+48y-64[/tex]

The degree of freedom is 2
