Step 1 
Given: 
Polynomial of lowest degree with zeros of -2 (multiplicity 2) and 3(multiplicity 2) 
and with f(0)=-108. 
Step 2 
The polynomial equation is provided by:
f(x)=A(x+2)2(x2)3 
When, x=0, f(0)=-108: 
108=A(0+2)2(02)3 
108=A(2)2(2)3 
108=A(4)(8) 
108=32A 
Step 3 
10832=A 
3.375=A 
A=3.375 
f(x)=3.375(x+2)2(x2)3

Step 1 
To find a polynomial f (x) with integer coefficients that satisfies the requirements
Step 2 
Polynomial of lowest-degree 
with zeroes of -2 multiplicity 2...(i) 
zeros of 3 multiplicity 3...(ii) 
f(0)=-108 
i*e, (x+2)2=0 
(x3)3=0 
or f(x)=A(x+2)2(x3)3 
f(0)=A(4)(-27) 
-108=A(-108) 
A=1 
f(x)=(x+2)2(x3)3 
Is the polynomial with degree of 5.

Solution: zeros of -2 (multiplicity 2)
zeros of 3 (multiplicity 2)
f(0)=108f(x)=k(x+2)2(x3)2f(0)=108=k(4)(9)=36kk=10836=3f(x)=3(x+2)2(x3)2
