Question

Help please. Fan & medal
Pre calc

Answer 1

Solve : 3x^2 + 5x + 13 = 0
Use Quadratic formula= -b +/- √b^2 - 4ac/2a

Answer 2

I got -5 +/- √-131/6 is this correct?

Answer 3

Or can you simplify

Answer 4

That is it.

Answer 5

you still have to solve

Answer 6

No that is all its asking for as long as you cant simplify it

Answer 7

\[\Large x = \frac{ -5 + \sqrt{131} }{ 6 }~or~\frac{ -5 - \sqrt{131} }{ 6 }\]

Answer 8

Thanks

Answer 9

If it wants answer in decimal, then you can use your calculator. Otherwise leave it as is.

Answer 10

-5+-sqrt(25^2-4(3)(13))/(2(3))
-5+-sqrt(469)/(6)

Answer 11

sorry, i missed the negative sign. So there has to be an "i" outside the square root.

Answer 12

\[\Large x = \frac{ -5 + i\sqrt{131} }{ 6 }~or~\frac{ -5 - i\sqrt{131} }{ 6 }\]

Answer 13

yes thats it haha :)

Answer 14

that is not right ranga

Answer 15

I forgot my i too

Answer 16

@clydesdalecup , b = 5 which when squared is 25. You have squared 25 instead.

Answer 17
