here are my options: (c + 2)2 (c + 1)(c + 4) (c2 + 4)2 The expression cannot be factored because it is prime.

(c + 2)^2? @triciaal

Change 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?

1x^2 + 4x + -4?
Bananas1234
  • Bananas1234
wait sorry wrong formula
Bananas1234
  • Bananas1234
D = 4^2 - 4 times 1 times -4??
jim_thompson5910
  • jim_thompson5910
Yes now evaluate that to get D = ???

32??
jim_thompson5910
  • jim_thompson5910
is that a perfect square?
Bananas1234
  • Bananas1234
no.....
jim_thompson5910
  • jim_thompson5910
since D = 32 is not a perfect square, that means the original expression cannot be factored. It is considered "prime"

ohhh i see!!
