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.

To get the solutions, we must first apply the quadratic formula to the equation above. 

 

The quadratic formula is: b+b24ac2a where a is the coefficient of x2b is the coefficient of x, and c is the constant.

 

Now to apply it.

31+961100812 

Now we have the two solutions.

 

Here they are:

 

31+i4712 , 31i4712
