What is 4x-x2?
4x-x2 = 2
How do you factorise x2 plus 4x?
X2 + 4xx(x + 4)=======
What must be added to 3x-7 to make x2 4x -1?
x2 + x + 6
What is x cubed minus 4 x squared plus 7 x divided by x equals?
[ x3 - 4x2 + 7x ] / (x) = x2 - 4x + 7
How can you simplify x2 plus 2x-35x2 plus 4x-21?
It is: 4x -34x^2 -21 simplified
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 4x-x2?
4x-x2 = 2
What are the factors of x2 - 4x?
-2
X squared 4x 4 divided by x 2 can i have a step by step answer?
(x2 + 4x + 4)/(x + 2) Is this the correct question? And what are you asking?
How do you simplify the equation x2 plus 4x-5 divided by x plus 5 I am stuck?
x+5 is a factor of x2+4x-5 use synthetic division to learn that the other factor is x-1
Factor x2 - 4x - 32?
x2 - 4x - 32 = (x - 8)(x + 4)
Is x2 - 4x -12 prim?
No. x2 -4x - 12 = (x + 2)(x - 6)
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
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
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
What is a common factor of x2-16 and x2-4x?
x2 - 4
What is x squared minus 4 divided by 4x plus 12?
(x2 - 4)/4x = 12; x ≠ 0 x2 - 4 = 48x x2 - 48x = 4 x2 - 48x + 242= 4 + 242 (x - 24)2 = 4 + 576 x - 24 = ±√580 x = 24 ± 2√145
