Question

need help with quadric equations please
!

Answer 1

\[-1 +/- \sqrt{-15}/ 2\]

Answer 2

what is the equation?

Answer 3

I just listed it above--I already filled in the numbers and broke it down the the best of my ability. it is simplifying radicals on the right side that I am stuck on...

Answer 4

the +/- part is where they are a fraction--one over the other. did not find a button to set it up that way. haha don't want to cause any confusion. the other slash line is the fraction line where 2 is the denom

Answer 5

\[(-1+i \sqrt{15})/2\] and
\[(-1-i \sqrt{15})/2\]

Answer 6

the answer was -1, -4

Answer 7

how did they get that?

Answer 8

The original problem was x^2+5x+4?

Answer 9

If so then the quadratic equation says: [-5+-√(5^2-4(1)(4))] / 2(1)
(-5+-√(25-16))/2
(-5+-√(9)) / 2
(-5+-3)/2
which is x = -1, -4
