Answer:
(3,0), (4,0)
Explanation:
First, let us factor this quadratic. I have a methody that may be different.
First, AC=12
Then, two numbers multiply to twelve and add to -7. They are -3, and -4. Then, switch the signs and divide by the coefecent of x^2, whihc is 1. so, the x intercepts are 3, and 4 from the equation (x+3)(x+4).
