Swimming space. The length of a rectangular swimming
pool is 2x - 1 meters, and the width is x + 2 meters. Write
a polynomial A(x) that represents the area. Find A(5).
I have the polynomial being:
If I find A(5):
Is this right?
You left out the constant term after you expanded
A(x) = (2x-1)(x+2)
it should have been 2x^2 + 3x - 2
adjust A(5) accordingly
