Question 1130007: Factor the polynomial f(x)=x^3+5x^2-2x-10 into linear factors using two methods: Grouping method and rational zeros

"Grouping" Method

Synthetic Division, Check for Possible Roots:
A few roots to try, but...


-5    |    1    5    -2    -10
      |
      |        -5     0     10
      |______________________________
          1    0    -2      0

Shows that works so is one factor, and the resulting quotient shows is a the other factor.
