y=x^2+x+1 and y=x
Do I just have to factorise the quadratic??

c1? looool more like fp1
Just make the x^2+x+1 equal to the x (as they both equal y), move the terms across and then factorise

I did that and it gives my x^2 +1 , but how do I solve the quadratic

the question is wrong because the answer would be x=i but as youre saying its c1 i doubt thats an actual question

are you sure its no minus 1? Because then you could do (x+1)(x-1) = 0

Yeah I think the question is wrong, we haven't done imaginary numbers in core

It definitely positive

Same thoughts here. I agree too. You would have x being a complex number.
