i would say that x = 4
* * * * *
I, on the contrary, would say that x = 4 or 0.
The equation is:
2x2 - 8x = 0;
and it factorises as:
2x(x - 4) = 0; whence,
x = 4 or 0.
Also, you can check your result:
2(0)2 = 0 = 8(0); and
2(4)2 = 32 = 8(4).
This shows that we must be doing something right.

Factor 2x squared plus 8x plus 6?
2(x + 3)(x + 1)
What is the answer to 8x - 4 equals 2x - 3?
x = 1/6
How do you factor 4x squared - 16?
(2x + 4)(2x - 4) to check your answer, use the FOIL method (first, outside, inside, last) F.... 2x x 2x = 4x^2 0.... 2x x -4 = -8x I..... 2x x 4 = 8x L.... 4 x -4 = -16 so 4x^2 - 16 = (2x + 4)(2x - 4)
How do you work out 8x plus 6 equals 2x plus 24?
8x + 6 = 2x + 24 To solve, collect like terms on each side; collect the x's on the left, the numbers on the right: 8X + 6 = 2x + 24 8x - 2x = 24 - 6 6x = 18 6x / 6 = 18 / 6 x = 3
Solve for x 6x - 7 equals 8x plus 9?
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
What is 2x x 4x x x?
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
What is 6-2x equals 8x?
If: 6-2x = 8x Then: x = 3/5 or 0.6
What is the solution to the simultaneous equations of y plus x squared equals 8x and y equals 2x?
y + x2 = 8x y = 2x Substitute from the second equation into the first: 2x + x2 = 8x Subtract 8x from both sides (and change order): x2 - 6x = 0 x(x - 6) = 0 So x = 0 which gives y = 0 or x = 6 which gives y = 12
-30-2x equals 6-8x what is x?
x=6.
Solve for x 8x equals 2x plus 15?
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
What does 8x-5-2x-15 equals?
x=5
8x plus 2x equals 90?
x = 9.
8x - 4 - 2x equals -10?
x= -1
How do you factor x squared -2x-3 equals 0?
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
What is the answer of 8x plus 16 equals 6x?
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
Solve 8x plus 39 equals 2x-15?
8x+39 = 2x-15 6x = -54 x = -9
How do you sovle the equation of 8x plus 4 equals 2x plus 28?
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
