I am having trouble with these. I don't even know where to start:

Find the exact solutions to 6x^2+x+4=0 By using the Quadratic Formula.

Find the value of the discriminant for 9x^2+1=6x. Then describe the number and type of roots for the equation.

Thanks =)

In the second, put the quadratic in standard form (ax^2 +bx +c), and compute the descriminant.
