The question is ambiguous and two possible answers are given below:
2x2 - x2 = x2
or
(2x)2 - x2 = 4x2 - x2 = 3x2
(x + 2)(x - 4)
x(x - 2)
The power law of indices says: (x^a)^b = x^(ab) = x^(ba) = (x^b)^a → e^(2x) = (e^x)² but e^x = 2 → e^(2x) = (e^x)² = 2² = 4
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
2(x - 7)(x - 1)
2(x + 2)(x - 2)(x2 + 2x + 4)(x2 - 2x + 4)
x4+6x3-2x-12 (x3-2)(x+6)
3x3 - 3x2 + 2x - 2 = 3x2(x - 1) + 2(x - 1) = (3x2 + 2)(x - 1)
(x - 2)(x + 2)(x2 - 2x + 4)(x2 + 2x + 4)
(x - 2)(2x + 3)
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.
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
(2x - 3)(3x + 2)
Factors are (x + 4)(x - 2) so x = -4 or 2
x^2 - 2x = 0 x(x - 2) = 0 x = 0 or x = 2
x2 - 2x = x(x - 2)
X=27
