Step 1
If a, b, c and d are the zeroes of polynomila f(x) of degree 4 then the polynomial f(x) = (x - a)(x - b)(x - c)(x - d)
Step 2
In this case, the roots are 5 (multiplicity of 2), -6, 0
hence a = 5, b = 5, c = -6 and d = 0
Hence, f(x) in the factored form = (x5)(x5)(x+6)(x0)=x(x5)2(x+6)

Answer:
f(x)=(x5)2(x+6)x
Explanation:
To find a polynomial f(x) of degree 4 with the given zeros, we can start by considering the factored form of a polynomial. The factored form is given by:
f(x)=a(xr1)(xr2)(xr3)(xr4),
where r1,r2,r3, and r4 are the zeros of the polynomial and a is a constant.
Given the zeros 5 (multiplicity 2), -6, and 0, we can substitute these values into the factored form. Using this information, the polynomial f(x) becomes:
f(x)=a(x5)(x5)(x+6)(x0).
To determine the value of a, we need additional information. Let's assume that the leading coefficient of the polynomial is 1. This means that a=1.
Therefore, the polynomial f(x) can be expressed as:
f(x)=(x5)(x5)(x+6)(x0).
Expanding this expression, we get:
f(x)=(x5)2(x+6)x.

To find a polynomial f(x) of degree 4 with the given zeros, we can use the fact that the polynomial can be expressed as the product of linear factors corresponding to each zero.
The zeros are: 5 with multiplicity 2, 6, and 0.
The linear factors are:
- x5 (for the zero 5 with multiplicity 1)
- (x5)2 (for the zero 5 with multiplicity 2)
- x+6 (for the zero -6)
- x (for the zero 0)
Now we can multiply these factors together to get the polynomial f(x):
f(x)=(x5)(x5)(x+6)(x)
Simplifying further:
f(x)=(x210x+25)(x2+6x)
Expanding this expression:
f(x)=x44x390x2+150x
Therefore, the polynomial f(x) of degree 4 with the given zeros is:
f(x)=x44x390x2+150x

Using the zero-product property, we can write the polynomial f(x) as the product of its linear factors:
f(x)=a(xr1)(xr2)(xr3)(xr4),
where a is a constant and r1,r2,r3, and r4 are the zeros of the polynomial.
In this case, we have the zeros 5 (with a multiplicity of 2), -6, and 0. Therefore, we can write:
f(x)=a(x5)2(x+6)(x0).
To determine the value of the constant a, we can use one of the given zeros. Let's use x=0 and substitute it into the polynomial:
f(0)=a(05)2(0+6)(00).
Since f(0) is equal to 0 (one of the given zeros), we can solve for a:
0=a(5)2(6)(0).
Simplifying, we get:
0=a(25)(6)(0).
Since any number multiplied by 0 is equal to 0, we have:
0=0.
This equation is always true, regardless of the value of a. Therefore, we can choose any value for a.
Let's choose a=1. Then the polynomial f(x) becomes:
f(x)=(x5)2(x+6)x.
Thus, the polynomial f(x) of degree 4 with the given zeros is:
f(x)=(x5)2(x+6)x.
