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

By collecting like terms: 8z+4-2x
-3
the answer to this problem is -2x^2y^2
Like terms are: 5x -7x +2x and 3 -5
