Question

In Desmos, using the Rational Root Theorem type the equation 2x³+ 5x²- 4 -3

which of the following match the possible roots that are NOT the actual roots of the function?

Answer 1

$2x^3+ 5x^2- 4x -3 \\ p= ± 1, ± 3 \\ q= ± 1, ± 2 \\ Possible \ rational \ roots \ are: \ x=p/q=±\{1,3,\frac{1}{2},\frac{3}{2} \} \\ Answer: \ x=-1, \ 3, \ \frac{1}{2}, \ \frac{3}{2}, -\frac{3}{2}$
