 Question 136458: Once again, I am in need of your help. I am stuck on a quadratic equation that I have to graph... and out of 16 problems on this worksheet, this is the only one I have not been able to solve. This is not from my book, this is off of a worksheet. This is what I have so far: y= x^2 + 2 a=1 b=0 c=2 a=1 > 0 parabola opens upwards x=0 y=0^2 + 2 y-intercept is (0,2) y=0 0=x^2 +2 x= -0±√(0^2-4(1)(2) ------------------------------- 2(-1) x= 0±√(0-8) ----------------- 2 X=0 and this is where I am stuck at. I am sorry your page is not allowing me to use the proper quadratic equation form. I did the best that I could. Would you please help me work through this?
