There are some operators missing that make this rather ambiguous.
If you mean:
3x - 111 + x2 = x
and wish to solve for x, then here's the answer:
x2 + 2x - 111 = 0
x2 + 2x + 1 = 112
(x + 1)2 = 112
x + 1 = ± √112
x = -1 ± 4√7
If you mean:
3x - 111 = x2 + x
Then solving for x gives us this:
x2 - 2x + 111 = 0
x2 - 2x + 1 = 112
(x - 1)2 = 112
x - 1 = ± √112
x = 1 ± 4√7
If you mean:
3x - 111 + x2 + x
And want to simplify it, that would be:
x2 + 4x - 111
Not much really, as it can't be factored further.

How do you slove x2-25x plus 24?
Factorise to (x-1)(x-24)=0 then either x-1 = 0 or x-24 = 0 so x=1 or x=24
How do you answer this algebra problem X2-4x-12?
x2-4x-12 = (x-6)(x+2) when factored
What is the least common multiple of x2-1 and x-1?
Since x2 - 1 is a multiple of x - 1, it is the LCM of this problem.
What is the solution of x2-x-4 equals 0?
have to put it was 2x and not x2--back to the problem--2x-x-4=0x=4* * * * *True, but the question, in all likelihood WAS x2 - x - 4 = 0and the solutions to that equation are -1.561553 and 2.561553
Solve for x 10 x2 plus 2x 6?
You will need to use the FOIL formula to write this problem and begin solving it for X.

Please slove the problem below by completing the square and show all work X squared plus two x equals seven?
x2+2x = 7 Completing the square:- (x+1)2 = 7 (x+1)2-1 = 7 (x+1)2 = 8 x+1 = -/+ sq rt 8 x = -1-/+ sq rt 8
How do you answer the problem x2 plus 10x plus equals 0?
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
Another math problem Factors x³ plus 1?
(x + 1)(x2 - x + 1)
Can x squared and x be combined?
The question is imprecise ... the concept of 'combined' needs further definition. How do you want them combined ? By addition ? . . . . . x2 + x = x (x + 1) By subtraction ? . . . . . x2 - x = x (x - 1) By multiplication ? . . . . . (x2) (x) = x3 By division ? . . . . . x2 / x = +x or -x By exponentiation ? . . . . . (x2)x = x2x = 102xlog(x) We don't see any problem with any of these mathematical combining methods, nor with any mechanical method, such as tying or gluing them together.
How do you solve for the problem x squared minus 10 equals 4x plus 11?
x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7
