This is an expression and not an equation (because there is no equals sign), so it can not be solved, only factored.
4X - 2
2(2X - 1)
=======
Assuming that you meant 4x - 2 = 0 Now that it's been factorized, you can see that there are 2 factors; 2 and 2(2x-1)
You have a definite value of 2, but you need to equate what's inside the brackets to 0.
so, 2x -1 = 0
What number multiplied by 2, and taken 1 from, results in zero?
The answer is 1/2 (a half, 0.5)
Why? -Well, 2 times 1/2 is 1.
And it logically follows that 1-1 = 0
We can now say that there are 2 values for x.
We write it like this as a final answer:
x=2, x=1/2

No, it has factors... 4x2 + 8x -21 = (2x+7)(2x-3)
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
4(x^2 + 2x + 8)
When simplified it is: 1-8x
No, it has factors... 4x2 + 8x -21 = (2x+7)(2x-3)
3x-3x+4x^2+8x=4x^2+8x
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
4(x + 1)(x + 1)
4(x^2 + 2x + 8)
When simplified it is: 1-8x
It is probably 2.
(2x - 1)(2x + 5)
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
dont know sorry
1/2 , 3/2
