\\ \sf\longmapsto B(x+2)=(x+2)(x+3)

  • Cancel x+2

\\ \sf\longmapsto B=x+3

Answer:

Step-by-step explanation:

Not directly. But the quadratic formula can do it. But that's not your question.

the factors you get must contain the factors for 1 which are 1 and - 1

These factors must add to - 5. There's no way that will happen with 1 and - 1 and you would be creative math if you tried to say that you could make one of the factors (x -1-1-1-1-1-1). That creates a whole new question.
