Answer:

p(x) =  {x}^{4}  +  {x}^{3}   - 7 {x}^{2} - x + 6

Step-by-step explanation:

The polynomial function has zeros

x=1, x=2,x=-3,x=-1

This means the factored form of the polynomial is

p(x) = (x - 1)(x + 1)(x + 3)(x - 2)

We expand to get:

p(x) = ( {x}^{2}   - 1)( {x}^{2}  + x - 6)

We expand further to get:

p(x) = {x}^{2}( {x}^{2}  + x - 6) - 1({x}^{2}  + x - 6)

p(x) =  {x}^{4}  +  {x}^{3}  - 6 {x}^{2}  -  {x}^{2}  - x + 6

This simplifies to:

p(x) =  {x}^{4}  +  {x}^{3}   - 7 {x}^{2} - x + 6

This is the standard form of the polynomial since it is written in descending powers of x.

Gala2k [10]

Answer:

The Answer is C.

Step-by-step explanation:

There is only one number before the decimal point, 6. 6 ones, so we already cross out A and D as incorrect. Now we have B and C. There is only two numbers after the decimal point. The first number after the point is in the tenths place. So, B is the correct answer.
