Question

Rational Root Theorem: What would the constant be?
0 or -31.5 or I am just missing this completely?
31.5=x^3+4x^2+3.75x?

Answer 1

the rational roots theorem only applies when all the coefficients are integers. So you might want to multiply everything by 4 to get rid of the decimals.

Answer 2

would I move the 31.5 to the other side so it becomes 0=x^2+4x^2+3.75x-31.5?

Answer 3

yes. and then multiply everything by 4.

Answer 4

Great. Thanks!
