Answer:
(x -1)(x -2)
Explanation:
You want factors of 2 that sum to -3. The positive sign on +2 tells you they both need to have the same sign. The only two negative integer factors of 2 do that.
2 = (-1)(-2) . . . . (-1) + (-2) = -3
Hence these are the numbers (-1, -2) that go in the binomial factors.
