If you know how to "do" this, how can you not know how to get the answer?

Please clarify. When you reply, please include the complete instructions for this exercise, a listing of all of the steps you have tried, and a definition of what you mean by an "incomplete" quadratic equation. Thank you.

remember to subtract 22 to the other side before solving and then use the quadratic formula.

-b +or- the square root of ((b^2) -4ac)
all divided by 2a

good luck!

You don't need the quadratic equation. It factors.
3x²+5x-22=0
The factors are 1&3 and 2&11
so they look like
(3x?11)(x?2)
The 5 is positive so the larger product is positive.
(3x+11)(x-2)=0
Are the factors.
