Question

write a third degree polynomial function in standard form with 2 as a root

Answer 1

x^3-8=0
Knowing when you plug 2 in, it will be cubed into an 8 so just subtract 8 to make it equal zero:
x^3=0
x=2 so (2)^3 = 8
make it balance so bring the 8 to the left side for standard form.
x^3-8=0 when x=2.

Answer 2

thank you
