The area of a rectangular living room is 2x squared plus 3x - 20 square feet
Write the dimensions for the living room in terms of x.
-----------------
Area = 2x^2+3x-20
Factor:
Area = 2x^2+8x-5x-20
Area = 2x(x+4)-5(x+4)
Area = (x+4)(2x-5)
========================
1st dimension: x+4
2nd dimension: 2x-5
=========================
