It is: 2x(2x+11)

There appears to be no equation in the question: only some disjoint expressions. Expressions cannot be solved.

These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.

Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).

(16 + 4x)/2 2(4 + x)

Without any equality signs the given expressions can't be considered to be straight line equations but in general parallel straight line equations will have the same slope but different y intercepts.

The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.

Depending on the missing operational sign, that would be 2(x plus or minus 8)

You need at least two expressions to find something in common between them. The GCF of 2x and 10 is 2.

2(4x+8) 4(2x+4) 8(x+2)

2x + x + 2x + x = 6x

8x-4

No because without any equality signs the given expressions can't be considered to be equations

3x2 has x, x2 , and 3 as factors. 2x-5 does not have any of those as factors. So the greatest common factor is 1. If you were adding rational expressions with those two expressions in the denominator, you would need to multiply them together to find the least common denominator.

3x + 2x - 8x + 2x = -x

2x squared plus 2x plus xy plus y or 2x(x+1) + y(x+1) or (x+1)(2x+y)

x=1

You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.

It is 2x+(-2x) = 0

The LCM is 2x + y

-2x + 6 + 22 = -2x + 28

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "is less than", "is greater than". The question contains two expressions but there is no visible symbol between 5x and 2x so that there is no inequality that can be solved.

Sample Answer: To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove equivalence.

6 + 2x + 5 = 11 + 2x
