Where are you asking about adding or subtracting?
anonymous
  • anonymous
well with \[1\pm \sqrt{1^2 -4(1)(-4)} \] would this be a situation to add since a neg 4 times a neg 4 is a positive 16

Yes. You would add.

okay beacuse in my math book there is a similar one and they subtracted. it was \[-2 \pm \sqrt{2^2 - 4(5)(-2)} \over 2(5)\]

Well, you add inside the square root for both cases because you're multiplying two negative numbers together.

right but the answer in the book depends on it being subtracted. So is the book just plain wrong?
