Answer:

X=-2, X=-3

Step-by-step explanation:

The original formula would be x^2+bx+c. I factored out the problem and made a t chart that multiplies to 6 (a*c) and adds to 5 (b). 3 and 2 are the only ones that add to 5 and multiply to 6. I then grouped x^2+3x+2x+c because the c doesn’t change And 3x+2x are the multiples. Then i took out common terms and got (x+2)(x+3)=0 because we solve for x. Then when you move them you get -2 and -3 equal x. Hope it helps you.
