I need to find out how to input the code for the above question. I know that I need to enter B minus C but how do I find the complement of a set in Maple?
Hi, I'm trying to complete two questions. One question is using maple 'to solve the following systems of equations': y=2x-5,y=2x^2+2x-21 I have entered the following code: solve({y=2*x-5,y=2*x^2+2*x-21},{x,y}); The output I get is this: {x = 2*RootOf(-2+_Z^2, label = _L14), y = 4*RootOf(-2+_Z^2, label = _L14)-5} I have no idea what this means apart from the fact that it's wrong but i'm not sure where I have gone wrong. The other question involves expanding the bracket (2x-3)^5 I've input: expand(2*x-3)^5; The output I get is: (2*x-3)^5 Surely this is wrong???!
