Question

the area of a rectangle rug is given by the trinomial r²-6r-55. what are the possible dimensions of the rug? use factoring.

Answer 1

Factor the trinomial to get width and length.

r² - 6r - 55 = (r - 11)(r + 5)

You have the factors r-11 and r+5. One of these can be the width, and the other must be the length.

Answer 2

r² - 6r - 55 = (r - 11)(r + 5)

The dimensions are the factors

r - 11

r + 5
