You can't possibly factor that expression since there is no common factor!

I hope this helps!

Factorise y^2+2y-1 first until its (y-something)(y+something)
then its like x^2+(y-something)(y+something)
Usually simultaenous equations like this have 2 equations and your suppose to solve it simultaeneously...
like maybe they might give x= y-1 or something and you sub it in.
since only have lidat then you factorise the only thing that you can factorise lor...
they also never give you what is x.
stupid question
