 Question 436855: Solve the equation by completing the square. The equation has real number solutions. 4p^2-32p+29=0 Click here to see answer by Edwin McCravy(8880)

 Question 437355: Hi, I need help solving radical equations. I tried one and got nowhere and did a second one and came up to the same thing. Here is the first on that I didn't understand. (x^(3/2)-3x^(1/2)=0 And here is the second one. (x^(1/2)-2x^(1/4)+1=0 Any help would be great. One more question. Do you know of a link to a page where I could read more on these type of radical equations that deal with fractions? Thanks for all your help! Click here to see answer by Gogonati(809)
