5x - 4x = x
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.
x^2-4x/x^2-6x+8 = x(x-4)/(x-2)(x-4) = x/(x-2)
x - 2
I assume you wanted this factored: (x+6)(x-2)
x2 - 4x - 21 = (x-7)(x+3)
5x - 4x = x
4x + 20
x(4x-2)
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
x3 - 4x = x(x2 - 4) = x(x + 2)(x - 2)
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
3x - 5x + 4x = -2x +4x = 2x

The slope of f(x) = 3-4x is -4.
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
x2-4x-165 = (x-15)(x+11) when factored
