Answer 3

To solve the quadratic equation 2x^2 - x(2x - 5) - 2(2x - 1) - 5 = 0, follow these steps:

Step 1: Distribute and simplify the equation: 2x^2 - x(2x - 5) - 2(2x - 1) - 5 = 0

First, distribute the terms inside the parentheses:

2x^2 - 2x^2 + 5x - 4x + 2 - 5 = 0

Now, simplify the equation:

x - 3 = 0

Step 2: Isolate the variable x:

x = 3

So, the solution to the equation is x = 3.
