This is a Polynomial. The area of the triangle is represented by the expression 1/2(x^3-2x+2x^2-4). The height of the triangle is x+2. Write anexpression for the base of the triangle. (Hint: The formula for the area of a triangle is A=1/2bh.)
Factoring the polynomial - without the leading fraction - we have
x^2 (x + 2) - 2(x + 2) =
(x^2 - 2) (x + 2)
So we have
A = (1/2)(b)(h) =
A = (1/2) (x^2 - 2 ) (x + 2)
So the base is represented by
(x^2 - 2)
