The solution
You have entered
[src]
(3*x - 2)*(3*x + 4) = 3*(x + 1)*(3*x + 1)
$$\left(3 x - 2\right) \left(3 x + 4\right) = 3 \left(x + 1\right) \left(3 x + 1\right)$$
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 11$$
Divide both parts of the equation by -6
We get the answer: x = -11/6
(3*x-2)*(3*x+4) = 3*(x+1)*(3*x+1)
Expand expressions:
-8 + 6*x + 9*x^2 = 3*(x+1)*(3*x+1)
(3*x-2)*(3*x+4) = 3 + 9*x^2 + 12*x
Reducing, you get:
-11 - 6*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 11$$
Divide both parts of the equation by -6
x = 11 / (-6)
We get the answer: x = -11/6
