Question 292213: Find x- and the y- intercept of .
Here's what I've got so far:
y-int:
y=3(0)^2 + 5(0) - 2
so y=0+0-2
so y+-2
and for the x-int:
0=3x^2+5x-2
here's where I get lost.
Do I add 2 to each side and then try to square out the remaining components? If so, how do I go about that? Because I'm confused at this step.
Any help is appreciated, thank you!
