The solution
You have entered
[src]
(4*x - 3)*(4*x + 3) - 2*x*(8*x - 1) = 0
$$- 2 x \left(8 x - 1\right) + \left(4 x - 3\right) \left(4 x + 3\right) = 0$$
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 9$$
Divide both parts of the equation by 2
We get the answer: x = 9/2
(4*x-3)*(4*x+3)-2*x*(8*x-1) = 0
Expand expressions:
- 9 + 16*x^2 - 2*x*(8*x - 1) = 0
- 9 + 16*x^2 - 16*x^2 + 2*x = 0
Reducing, you get:
-9 + 2*x = 0
Move free summands (without x)
from left part to right part, we given:
$$2 x = 9$$
Divide both parts of the equation by 2
x = 9 / (2)
We get the answer: x = 9/2
