3x^2 + x = 2
3x^2 + x - 1 = 0
no integer solution, (use the formula, it will not come out to be a whole number)
If 3 times the square of an integer is added to 1 times the integer, the result is 2. Find the integer.

Wait Mr. Reiny, I think there is a typo.
3x^2+x-2=0
So there should be two roots
x= -1
x = 2/3
And since the question is asking for "integer", I guess only -1 works since 2/3 is a fraction which is not an integer.
