help with equation involving x^(3/2)

Postby mricks152 on Tue Jan 24, 2012 11:29 pm

I need to solve the following equation:

2x^2 + 15x^(3/2) + 155x + 75 = 0

Any ideas?

One might try restating the current variable and powers in terms of y = sqrt[x]:





Then apply standard techniques for solving polynomial equations.
