Consider the function y = 3x5 – 25x3 + 60x + 1. Use the first or second derivative test to test the critical points. How many relative maxima did you find?

So I put the derivative of 15x^4-75x^2+60 into wolfram-alpha and it got four critial points on the graph, but they're all equally leveled...so does mean there is no relative maxima or that there are four of them?
