x=-b+-sqrtb^2-4ac/2a

-1+-sqrt1^2-4(6)(4)/2(6)

-1+-sqrt-95/12

-1-95/12

-96/12

x= -8

-1+95/12

94/12= 7.8333..

[-8, 7.83](answer)

**mk-tintin**, Saturday, March 1, 2008 at 8:15pmdo u know cumplex numbers???as your sqrt is negative(b²-4ac=-95) you have to use cumplex numbers to solve this equation

**mk-tintin**, Saturday, March 1, 2008 at 8:31pmso 6x²+x+4=0 has no one solution(no one real solution but there are cumplex solution : it's (-1+-isqrt95)/12

**Doc of MH**, Thursday, May 8, 2008 at 11:47amsince a=6,b=1,c=4

=-B¡¾¡î(B©÷-4AC)/2A

"-1¡¾¡î(1©÷-4(6)(4))/2(6)

"-1¡¾¡î(-95)/12

so the roots are imaginary

"since the square root of "-1" is "I"

(yes the letter "I")

Then your roots are

"(-1+9.74i)/12 and (-1-9.74i)/12
