What is a quartic polynomial function in standard form with zeros -2,4,4,and 3
Travka [436]

We can simply multiply the roots together to find the original function.

(x + 2)(x - 4)(x - 4)(x - 3)

FOIL.

x^2 - 4x + 2x - 8(x - 4)(x - 3)

Combine like terms.

x^2 - 2x - 8(x - 4)(x - 3)

FOIL.

x^3 - 2x^2 - 8x - 4x^2 + 8x + 32(x - 3)

Combine like terms.

x^3 - 6x^2 + 32(x - 3)

FOIL.

x^4 - 6x^3 + 32x - 3x^3 + 18x^2 - 96

Combine like terms.

<h3>x^4 - 9x^3 + 18x^2 + 32x - 96 is the original function with the given roots.</h3>

For each of the solutions of the equations find two consecutive integers between which the solution is located.
adoni [48]

Using squares of integers numbers, it is found that the solution of the equation is located between the integers x = 1 and x = 2.

The equation given is:

x^2 = 3

The solution of the equation given is:

x = \sqrt{3}

The squares of the integers numbers until the square root of 3 are:

1^2 = 1

2^2 = 4

Since 1 < 3 < 4, the square root of 3, which is the solution to the equation, is located between the integers x = 1 and x = 2.
