For question 14, use Descartes' rule of signs to describe possible combinations of roots for the polynomial. 1h(x)=2x^3 +5x^2 - 31x - 15

Sagot :

[tex]2x^3+5x^2-31x-15[/tex]

there is only one change of sign so we have one positive root

and the solution is

[tex](x+0.4564)(x-3.158)(x+5.2)=0[/tex]
