The area of a rectangle can be represented by the expression x 2+ 6x – 40. Write each dimension of this rectangle as a binomial, and then write the area in terms of the product of the two binomials

Question

Please explain the steps too :)

Answer 1

x^2 + 6x -40 = (x+10)(x-4) = Area, just factor the trinomial

length = x+20, width = x-4, x>4
