Best ResponseYou've already chosen the best response.1Ok, the first one is a parabola, if you put y to one side, you'll get \[2x^24x1=y\] the second one is a linear function, if you put y to one side, you'll get \[y=x+1\] By using the comparaison method \[y=y~~hence~~2x^24x1 = x+1\] \[2x^24x1 = x +1\]

Best ResponseYou've already chosen the best response.1\[2x^24x1 = x +1\]\[2x^24x11 = x\]\[2x^24x2+x =0\]\[2x^23x1 = 0\] Then solve for x by using the quadratic formula, you'll find two x's, since it's the system is something like this: dw:1335839518743:dw
