Question

Factor Completely:
r^2 -2r + 36

Steps please.

anonymous · Answer

seems unlikely that this will factor using integers

anonymous · Answer

you are not going to find two integers  whose product is 36 and whose sum is -2

anonymous · Answer

So I've noticed, how else can I factor this, is it doable?

anonymous · Answer

$$x=-b \pm \sqrt{b ^{2}-4ac}/2a$$

anonymous · Answer

you can factor it using complex numbers if you like

anonymous · Answer

use the format: $$ax ^{2}+bx+c=0$$ and fill in the equation, leave the square roots as square roots if needed

anonymous · Answer

$$2+\sqrt{4-4*36}/2$$ will give you one of them, change the + AFTER THE 2 to - for the other

anonymous · Answer

I'm completely lost, I haven't done complex numbers yet.. Let me try that though.

anonymous · Answer

you can probably leave it as$$ 2+\sqrt{-140}/72$$ I forgot to multiply 36 by 2 earlier

anonymous · Answer

and 2-... for the other

anonymous · Answer

I don't know how to get a square root for that, if I leave it as that how can I finish factoring the rest of the equation without a determined integer?
