4x - 2x = 2x
It is: x-4x = -3x
5x - 4x = x
x - 2
Would you mind typing it out for me? I don't quite understand exactly what you are asking. For example, x to the second power minus 4x over x to the second power minus 16 would be... x^2-4x/x^2-16 Do you mind typing it out like that? Because what you wrote makes no sense at all.
4x - 2x = 2x
It is: x-4x = -3x
4x + 20
5x - 4x = x
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
(4x-5)(4x+5)
x2 - 4x - 21 = (x-7)(x+3)
-14x
7x2 -4x -5x2 +2x = 2x2 -2x
(2x-1)(2x-1) = 4x^2 -4x + 1
Let 6x - 2x - 9 = a, where a is an arbitrary constant. Then 4x - 9 = a 4x = a+9 x = (a+9)/4
It is possible.
