Find the x intercepts for the graph of the equation y=x^2+3x-10 I have to find the s intercepts? Can you help

Start with the given equation

To find the x-intercept(s), let y be equal to zero. So plug in

Factor the right side (note: if you need help with factoring, check out this solver)

Now set each factor equal to zero:
or

or Now solve for x in each case

So the x-intercepts are:

and

Notice if we graph we can see that the x-intercepts are and . So this visually verifies our answer.
