x = - 0.5

x=-0.5

Step-by-step explanation

$2 x + 1 = 0$

$a_{n} = 2$

$a_{0} = 1$

Rewrite in standard form P(x)=0, then identify the leading and constant coefficients.

No rational candidate set is available; switch to a numeric solve for the remaining polynomial.

After deflation, solve the remaining factor using linear isolation.

$x = - 0.5$

All roots with multiplicity: x={-0.5}.
