Answer: 247.35
Step-by-step explanation:
Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.
factors of 20 are 1,2,4,5,10,20
factors of 1 are 1
so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
