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.
Factorise to (x-1)(x-24)=0 then either x-1 = 0 or x-24 = 0 so x=1 or x=24
x2-4x-12 = (x-6)(x+2) when factored
Since x2 - 1 is a multiple of x - 1, it is the LCM of this problem.
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
You will need to use the FOIL formula to write this problem and begin solving it for X.

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
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
(x + 1)(x2 - x + 1)
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.
x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7
If you want to know what its factors are, they are; (x-5y)(x+3y)

Original problem: x^2-x-20x2-25/x2-16x^2-x-30 Revised: [(x2 - x - 20)(x2 - 25)] / [(x2 - 16)(x2 - x - 30)] Solution: Factor the polynomials: {[(x - 5)(x + 4)][(x + 5)(x - 5)]} / {[(x +4)(x - 4)][(x - 6)(x + 5)]} Cancel common factors: [(x - 5)(x - 5)] / [(x - 4)(x - 6)] ---> Simplest form (or final answer) (Optional) Expand: (x2 - 10x + 25) / (x2 - 10x + 24)
