A rectangle has an area given by A=x^2+7x+2. Find expressions for the possible length and width of the rectangle.

  • Algebra -

    Well, Area >0

    A>0 so x^2+7x+2 >0
    (x+6.7)(x+.3)>0
    so a possible length is x+6.7 and a possible width is x+.3, and x can be any number >.3 ( as long as width is >0)

    check my thinking.
