It can be factored as 18(5-2x^2)
7+2n
Like terms are: 5x -7x +2x and 3 -5
5/ 2 -4/ 5 plus 2 expression can be written in simple form as 37/10.
2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5 = 60 - 40 - 5 = 15
12x + 5 - 2x =(12x - 2x) + 5 =10x + 5 =5 (2x + 1)
The expression goes like this: 2x+y+5-3. x and y are variables so we cannot perform unless we have a linear or simultaneous or as such equations.But operation can be performed if like terms are present, but in your problem the answer will be: 2x+y+2
It can be factored as 18(5-2x^2)
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
The browser used for posting questions on this site is mostly useless for mathematical questions since it strips out most symbols. It is, therefore, not possible to tell what the expression in your question is.
By collecting like terms: 8z+4-2x
7+2n
-3
the answer to this problem is -2x^2y^2
Like terms are: 5x -7x +2x and 3 -5
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.
