Find all solutions to the equation 6x^2 - 31x + 42 = 0.   If you find more than one, then list the values separated by commas. If the solutions are not real, then they should be written in a + bi form.

6x^2  - 31x  +  42   =  0

 

Quadratic Formula

 

x   =  ( 31  -  sqrt  ( 31^2  -4 * 6 * 42) ) / (2* 6)   =   ( 31  -  sqrt  (-47) )  /  12  =

 

31/12   -  [ sqrt (47)/ 12] i

 

Also

 

31/12  +   [ sqrt (47) / 12 ] i
