Question

what would be the solution of:

Answer 1

\[15+or -i \sqrt{144}/6\]

Answer 2

\[\frac{ 15+-isqrt{144} }{ 6}\]

Answer 3

Solutions:
-1 ± i

-1 ± 2i

-2 ± i

-2 ± 2i

Answer 4

I'm guessing the last one but idk

Answer 5

Separate it into 2 fractions. You get \[\frac{15}{6}-\frac{i \sqrt{144}}{6}\]This simplifies into 2.5-12i/6 = 2.5-2i

Answer 6

Are you sure it is 15?

Answer 7

Oh no im wrong! It's suppose to be a 6

Answer 8

wow thanks for pointing that out

Answer 9

Oh. Then it would be 6/6 = 1 +- 2i, so I'd pick the second answer. Are you sure it isn't -6, since all you answers are -1 or -2?

Answer 10

It was like this
\[\frac{ -(-6) squrt (-6)^2-4(3)(15) }{ 6}\]

Answer 11

Then I changed it to that

Answer 12

Alright, it looks like you did it correctly. So I assume the original polynomial was:
3x^2-6x+15?

Answer 13

Yep thanks for the help :)

Answer 14

YW.
