Answer 2

To solve the equation (2x - 3)² + (3 - 4x)(x + 5) = 82, follow these steps:

Step 1: Expand and simplify both sides of the equation.

Expand the left side: (2x - 3)² + (3 - 4x)(x + 5) = 4x² - 12x + 9 + (3x + 15 - 4x² - 20x) = 82

Now, combine like terms: 4x² - 12x + 9 + 3x + 15 - 4x² - 20x = 82

Simplify further: -12x + 3x - 20x = 82 - 9 - 15 -29x = 58

Step 2: Solve for x by isolating it on one side of the equation.

Divide both sides by -29 to solve for x: -29x / -29 = 58 / -29

x = -2

So, the solution to the equation is x = -2.
