real number solutions?

[hollerback1]

Hi, I have trouble with this types of problems.

2xsquared + 5x + 4 = 0

i got this far: 2xsquared +5x = -4

help me plz thanks.

Why are you moving the 4 to the other side of the equation, instead of just plugging into the Quadratic Formula? Or is there some particular method of solution that you're supposed to be using...?

Please reply with clarification. Thank you.

Eliz.

Oh...I guess i should use the quadratic equation.

Can you please show me how to do it?
