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.

8-2x2 equals x plus 22-7 in ax2 plus bx plus c equals 0 form?
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7

What is the answer to 2x2 x2?
2x2 is 4 and 4x2 is 8. The answer is 8. You could also look at it like 2^3, which is 2x2x2...and there is no need to separate the last 2 from the rest.
How many different 2 by 2 squares are on a chessboard?
Answer # 1If the 2x2 squares are mutually exclusive (i.e. non-overlapping), then the maximum number of 2x2 squares on a standard 8 x 8 board is 8x8 / (2x2) = 64 / 4 = 16.
What is the factor of X3 - 2x2 - 4x plus 8?
x3 - 2x2 - 4x + 8 = (x2 - 4)(x - 2) = (x + 2)(x - 2)(x - 2)
What is 2x2 plus 2x2?
4 + 4 = 8.Get it?You multiple the number 2 times and then you add 2.It's very confusing.
