The solution
You have entered
[src]
(4*x - 5)*(x + 3) = (2*x - 5)*(2*x + 5)
$$\left(x + 3\right) \left(4 x - 5\right) = \left(2 x - 5\right) \left(2 x + 5\right)$$
Detail solution
Given the equation:
Expand expressions:
Reducing, you get:
Move free summands (without x)
from left part to right part, we given:
$$7 x = -10$$
Divide both parts of the equation by 7
We get the answer: x = -10/7
(4*x-5)*(x+3) = (2*x-5)*(2*x+5)
Expand expressions:
-15 + 4*x^2 + 7*x = (2*x-5)*(2*x+5)
(4*x-5)*(x+3) = -25 + 4*x^2
Reducing, you get:
10 + 7*x = 0
Move free summands (without x)
from left part to right part, we given:
$$7 x = -10$$
Divide both parts of the equation by 7
x = -10 / (7)
We get the answer: x = -10/7
