Heres the quesion(adsbygoogle = window.adsbygoogle || []).push({});

Prove that the line whose equation is y=2x-1 does not intersect the curve with equation y=x^4 + 3x^2 +2x.

We are suppose to solve this using indirect proof, thus assuming the equations do intersect, and proving that wrong.

i let the y's equal each other, but that isnt getting me anywhere

where should i start.

thanks
