Need help solving these simultaneous equations, anyone with a pen and paper?

[Firepanda]

Solve

-r*(T^2 + T + 6) + 1 = 0

4r*(T^2 + T) - T = 0

For T and r

One solution is T=0 and r=1/6

There are 2 more.


I have T = +- i/(2)^0.5 and r = 1/[4(1+T)]

But MATLAB is disagreeing with my solutions, can anyone rectify them for me please?

ah nevermind, foudn my mistake early on, sorry for anyone bothering to attempt it I've done it (after 3 hours :/ )
