  A(x) = x(-x + 48)
  A(x) = x(-x) - x(48)
  A(x) = -x² - 48x
A(10) = -(10)² - 48(10)
A(10) = -100 - 480
A(10) = -580

  A(x) = x(-x + 48)
  A(x) = x(-x) - x(48)
  A(x) = -x² - 48x
A(20) = -(20)² - 48(20)
A(20) = -400 - 960
A(20) = -1360

  A(x) = x(-x + 48)
  A(x) = x(-x) - x(48)
  A(x) = -x² - 48x
A(28) = -(28)² - 48(28)
A(28) = -784 - 1344
A(28) = -2128

A(x) = x(-x + 48)
A(x) = x(-x) - x(48)
A(x) = -x² - 48x
A(0) = -(0)² - 48(0)
A(0) = 0 - 0
A(0) = 0
