Question

A farmer needs 3x2 − 4x + 10 seeds for each of x3 + 5x − 20 fields. What expression would represent the seeds the farmer needs to plant all of the fields? Is x = 1 a reasonable value for this representation? Complete the explanation.

Answer 1

Explanation:

(3x^2-4x+10)(x^3+5x-20) =
`3x^5-4x^4+25x^3-80x^2+130x-200`

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.
