Hello All...

How do I find the x intercept for $y = 2x^3 + 3x^2 - 12x + 8$

Then to find the intercept I've put y = 0... OR?

Thanks heaps

Are you sure you have the equation correct? There is only 1 real root and it has an ugly form.

Yes, I do.... I've double checked it... I realise it only has one x intercept due to the position of the cubic.

Thanks.
