Question

A square has sides of length s A rectangle is 6 inches shorter and 8 inches wider than the square. Express the area of the rectangle as a polynomial.

Answer 1

sides are s and s
s-6 times s+8
multiply
(s-6)(s+8) distribute
(s)(s+8)+(-6)(s+8)
s^2+8s+-6s-48
s^2-2s-48

area=s^2-2s-48 square inches
