yes they are because 4x is the same as x multiplied by 4 which is not the same as x-2

What is 4x-x2?
4x-x2 = 2
What is X2 divided by -4x?
6
How do you factorise x2 plus 4x?
X2 + 4xx(x + 4)=======
Why are not all functions linear equations?
Linear equations can be written as y = mx + b. Any other function would be non-linear. Some linear equations are: y = 3x y = 2 y = -2x + 4 y = 3/4x - 0.3 Some non-linear functions are: f(x) = x2 y = sqrt(x) f(x) = x3 + x2 - 2
What must be added to 3x-7 to make x2 4x -1?
x2 + x + 6
What is 4x-x2?
4x-x2 = 2
Can you complete the square factor and use the quadratic formula to solve these two equations x2-4x-21 equals 0 and x2-3x-18 equals 0?
x2-4x-21 = 0 => x = -3 or x = 7 x2-3x-18 = 0 => x = -3 or x = 6
What is X2 divided by -4x?
6
What are the factors of x2 - 4x?
-2
Factor x2 - 4x - 32?
x2 - 4x - 32 = (x - 8)(x + 4)
Is x2 - 4x -12 prim?
No. x2 -4x - 12 = (x + 2)(x - 6)
What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
Factor x2 plus 4x plus 6?
x2 + 4x + 6 can not be factored. If you want, you can reduce it to an expression with a single x term by comleting the square: x2 + 4x + 6 = x2 + 4x + 4 + 2 = (x + 2)2 + 2
Solve x2 - 4x - 9 equals 0 by completing the square?
x2 - 4x - 9 = 0 ∴ x2 - 4x = 9 ∴ x2 - 4x + 4 = 13 ∴ (x - 2)2 = 13 ∴ x - 2 = ±√13 ∴ x = 2 ± √13
X2 plus 1 divided by 2x4 plus 4x3 -x2 plus 4x-3?
You can work this out with long division, by checking to see if (x2 - 1) is a factor of (2x4 + 4x3 - x2 + 4x - 3). It is. Unfortunately, the WikiAnswers system is somewhat limited in depicting things such as long division, so we won't be able to represent it here. In short though, (2x4 + 4x3 - x2 + 4x - 3) / (x2 + 1) is equal to 2x2 + 4x - 3. which means that: (x2 + 1) / (2x4 + 4x3 - x2 + 4x - 3) = (x2 + 1) / (x2 + 1)(2x2 + 4x - 3) = 1 / (2x2 + 4x - 3)
What is a common factor of x2-16 and x2-4x?
x2 - 4
How do you factor x2 plus 4x-96?
x2 + 4x - 96 = (x - 8)(x + 12).
