Can someone do a step by step of how to solve for the x-intercept with this equations:
y=3x^2 + 4x - 6
y = x^3 - x^2 - x + 1
Hi Dickson,
The x-intercepts will be the zeros of the functions.
Looks like you'll have to use the quadratic formula on the first one.
On the second one, possible rational zeros are +1 and -1. See which one works using synthetic division and then solve the depressed quadratic for the other two zeros.
