maths help pleaseWatch
I'm really stuck on how to solve it have been trying for a while
What do you mean - "allowed to do that"? I haven't done anything yet, just expressed one term in an alternative form. You still have to square something and factorize and work out possible solutions...
i meant allowed to do that according to maths rules lol
=> x-y = 4(x-y)^2
=> x-y = 1/4
=> x= 1/4+y
For each value of y you will get a value of x.
