The area of a rectangular rug is given by the trinomial r^2-4r-77. What are the possible dimensions of the rug? Use factoring.

1 answer:

4 0

When you factor the equation...

r^2-4r-77

r^2+7r-11r-77

r(r+7)-11(r+7)

(r-11)(r+7) so each parenthetical term is a dimension.

Note that r>11 though for any possible real solution.
