finish it
help...I have been at the following for 3 hours and am so lost
I have the equation y=2x^2-7x-4 and I am trying to find the x and y intercept ( for a parabolla)
I have found the y intercept which is-4 but I`m lost on finding the x intercept, would I use the quadratic formula , if so am I correct that this way will give me both intercepts (x and y)
I have tried factoring the above to get x intercept but have got so confused.
not sure now which way to go

then you need to learn how to factor quadratic equations and how to use the zero product property ...
