Answer is x = 12 :)

Operations you're supposed to do in order to solve this equation are:

1. Combine like terms

2. Subtract 12 from both sides

3. Simplify

4. Divide both sides of the equation by the same term

5. Simplify.

Solve the quadratic equation 3x²+x-5=0
PIT_PIT [208]
This does not look easy to factor, so I'd suggest using the quadratic formula:
        -1 plus or minus sqrt( 1-4(3)(-5) )
x = -----------------------------------------------
                               2*3

         -1 plus or minus sqrt(61)
    = ------------------------------------
                             6

Thus, there are 2 real, unequal, irrational roots / solutions.
