polynomial equation

Do you know who I can solve this equation? c=delta*x^(-1/2)+b*x^(-2.2) in matlab??

You might want to look at the symbolic math toolbox..

Thanks THomas...but if I know the value for the parameters c, delta and b should I solve it in the same way??

[Walter Roberson]

That depends. Which of the 22 or more solutions do you want? And what does it mean to you to raise a negative number to the power 2.2 ?

Note: polynomials can only have nonnegative integer powers of variables, never square roots or powers such as 2.2
