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.

What is 8x times 2x?
To find the product of 8x and 2x, you multiply the coefficients (8 and 2) to get 16, and then multiply the variables (x and x) to get x^2. Therefore, 8x * 2x equals 16x^2.
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
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
Solve for x 8x equals 2x plus 15?
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
-30-2x equals 6-8x what is x?
x=6.
8x plus 2x equals 90?
x = 9.
What does 8x-5-2x-15 equals?
x=5
8x - 4 - 2x equals -10?
x= -1
What is 8x squared times 2x?
To solve the expression 8x^2 * 2x, you first multiply the coefficients (8 * 2 = 16). Then, you multiply the variables with the same base by adding their exponents (x^2 * x = x^(2+1) = x^3). Therefore, the simplified expression is 16x^3.
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 8x times 2x?
To find the product of 8x and 2x, you multiply the coefficients (8 and 2) to get 16, and then multiply the variables (x and x) to get x^2. Therefore, 8x * 2x equals 16x^2.
What is the answer of 8x plus 16 equals 6x?
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
