Question

if p=3,find 5he degree of the polynimial g(x)=(p-x)^3+14​

Answer 1

Answer:

3

Step-by-step explanation:

We know that

(a-b) ^3 = a^3 - b^3 -3ab(a-b)

then

(p-x)^3 = p^3 - x^3 -3px(p-x)

if p=3 then

(p-x)^3 = (3-x)^3= 27-x^3 -9x(3-x)

which is a polynomial of degree 3 then

g(x) is also a polynomial of degree 3 when p is equal to 3.
