The first factor is usually just found by trial and error. I mean, you could do bisection or Newton's method or something, but it's always fair to assume that these questions have whole number factors because they don't want the student getting caught up in stupid details. By the way, how is it you don't know how to do this? Are you ahead of the class or something? |

Uh, your solving it incorrectly Pull all of x on one side, and all numbers on the other. You end up getting the same result, but it's easier. |

This is a really poorly stated question if that's how it was given. This should actually have been given as the intersection of the lines y = -5x -9 and y = -5x - 8. Looking at it that way, it's obvious, without doing the math, that there is no solution, because the lines are parallel. |

Oh, it was a line intersect problem I hate y=mx+b format, I prefer parametric equations. |

Why is x=-1 a factor? |
