6x2-7x 8 -2x2 2x-2

Answer 1

This question doesn't make sense. Please choose your words wisely.

6x2-7x8-2x22x-2=-86

Still needs improvement: Either way, the first step is to add 2 to both sides. Now, are you saying 6x^2 - 7x^8 - 2x^(22x)=-84 or (6)(2)(x)-(7)(x)(8)-(2)(x)(22)(x)=-84?

The first possibility doesn't seem likely. For the second one: multiply everything to get this: 12x - 56x - 44x^2 = -84. Combine like terms and move everything to the right: 0= 44x^2 + 44x - 84. Divide everything by 4: 0= 11x^2 + 11x - 21. Use the quadratic formula: x=[-11±√(121+924)]/22. Simplify: x=[-11±√1045]/22. That is fully simplified. If this is not what you meant, I am happy to keep trying, just be as specific as possible. Use words and/or ^ by pressing shift and 6 on your keyboard at the same time.
