Can anyone formulate 5.3.2 and 5.3.4? I am having difficulties with these problems.

I'm not sure what to do for 5.3.2 either.

For #4 your can let p(x)=a(x)^n where n is odd and a is a coefficient. Then by 4.3.16 limp(x) as x-inf =inf and lim(p(x)) as x= -inf = -inf thus there exist x, such that p(x)>0 and x such that p(x)<0 then you can use the Root thereom. M. Niekamp

Does anyone know how to do #12 and #14?

That would be lovely.. I second this question.
