Best ResponseYou've already chosen the best response.0here are my options: (c + 2)2 (c + 1)(c + 4) (c2 + 4)2 The expression cannot be factored because it is prime.

Best ResponseYou've already chosen the best response.2Change all copies of 'c' to 'x' c^2 + 4c – 4 > x^2 + 4x – 4 x^2 + 4x – 4 is the same as 1x^2 + 4x – 4 so it is in the form ax^2 + bx + c where a = 1, b = 4, c = 4  Plug a = 1, b = 4, c = 4 into the discriminant formula D = b^2  4ac what do you get when you do so?

Best ResponseYou've already chosen the best response.2Yes now evaluate that to get D = ???

Best ResponseYou've already chosen the best response.2is that a perfect square?

Best ResponseYou've already chosen the best response.2since D = 32 is not a perfect square, that means the original expression cannot be factored. It is considered "prime"
