Answer 2

To solve the equation 2x^2 - 2x(x + 5) = 100, follow these steps:

Step 1: Expand the expression on the left side of the equation. 2x^2 - 2x(x + 5) = 100 2x^2 - 2x^2 - 10x = 100

Step 2: Simplify the equation. Now, the x^2 terms cancel out, and you are left with: -10x = 100

Step 3: Solve for x. To find the value of x, divide both sides by -10: x = 100 / -10 x = -10

So, the solution to the equation is x = -10.
