Answer 2

Let's solve the equation step by step:

Step 1: Expand the expressions on both sides of the equation. (х - 5)(х + 5) - 7х = (3 - х)^2 + 5

Step 2: Simplify the expanded expressions. (x^2 + 5x - 5x - 25) - 7x = (9 - 6x + x^2) + 5

Step 3: Combine like terms. x^2 - 25 - 7x = x^2 - 6x + 9 + 5

Step 4: Move all terms to one side of the equation to set it to zero. x^2 - 7x - x^2 + 6x - 39 = 0

Step 5: Combine like terms again. -x + 39 = 0

Step 6: Move the constant term to the other side. -x = -39

Step 7: Solve for x by dividing both sides by -1. x = 39

So the solution to the equation is x = 39.
