Can someone help me i dont know how to do this
Lynna [10]
Ok, there is no need to use a calculator for this.

Try and figure out what are the closest numbers for each one. For example, the first one, π, is lower than 4 but greater than 3. Therefore, it would be between 3 and 4.

What polynomial has roots of −6, 1, and 4?
tester [92]

Answer:

The correct option is C.

Step-by-step explanation:

polynomial has roots of −6, 1, and 4.

We can write it as:

(x+6)(x-1)(x-4)

Now multiply the terms:

First multiply first and second bracket:

{x(x+6)-1(x+6)}(x-4)

{(x^2+6x-x-6)} (x-4)

Solve the like terms:

{(x^2+5x-6)}(x-4)

x(x^2+5x-6) -4(x^2+5x-6)

x^3+5x^2-6x-4x^2-20x+24

Solve the like terms:

x^3+x^2-26x+24

Hence it is proved that the correct option is C....
