Answer:
![x^2 + x -12](https://tex.z-dn.net/?f=x%5E2%20%2B%20x%20-12)
Step-by-step explanation:
If the solutions are x=-4 and x=3, then it must have factors (x+4)(x-3). Assuming there is no GCF or leading coefficient other than 1, multiply with FOIL to find the standard form.
![(x+4)(x-3)\\x^2 + 4x -3x -12\\x^2 + x -12](https://tex.z-dn.net/?f=%28x%2B4%29%28x-3%29%5C%5Cx%5E2%20%2B%204x%20-3x%20-12%5C%5Cx%5E2%20%2B%20x%20-12)
