Question

p(x) =x3. find the following polynomial​

Answer 1

Answer:

P(x) = 3 - 6x

Zero of the polynomial...

3 - 6x = 0

-6x = -3

-x = -3/6

-x = -1/2

x = 1/2. ( Minus minus cancel)

_____________________________

p(x) = 5x - 3

zero of the polynomial ..

5x - 3 = 0

5x = 3

x = 3/5

Answer 2

Find p(0), p(1), p(2) for each of the following polynomials.

${\sf{\red{p(x) = {x}^{3} }} }$

${\mapsto} \: {\sf{p(0) = {0}^{3} = 0 }}$

${\mapsto}{\sf{ \: p(1) = {1}^{3} = 1 }}$

${\mapsto}{\sf{ \: p(2) = {2}^{3} = 8}}$
