Consider the polynomial 16x2 – 1.
Slav-nsk [51]

9514 1404 393

Answer:

  • ac = -16
  • b = 0
  • -4, 4
  • (4x -1)(4x +1)

Step-by-step explanation:

a) ac is the product of the leading coefficient (16) and the constant (-1).

  ac = (16)(-1) = -16

__

b) b is the coefficient of x. There is no x term, so ...

  b = 0

__

c) Two factors that add to give zero must be opposites. That is, they must be the square root of the opposite of -16, and the opposite of that.

  the two numbers are -4 and 4

__

d) The factored form for the two numbers p and q just found is ...

  ax^2 +bx +c = (ax +p)(ax +q)/a

  = (16x -4)(16x +4)/16

  = (4x -1)(4x +1) . . . . factored form of 16x^2 -1
