The area of a rectangular garden is given by the trinomial 2x squared + 2x - 84. What are the possible dimensions of the rectangle?

  • math -

    Begin by factoring out the common factor of 2.

    That leaves x^2 + x - 42

    Factor this trinomial

    Looks like you will be dealing with 6, 7. One is positive and the other is negative. Remember that distance cannot be measured as a negative number.
