Answer 2

To solve the quadratic equation 4x² + (3 - 2x)(3 + 2x) = 81x, follow these steps:

Step 1: Expand the product on the left side of the equation. 4x² + (3 - 2x)(3 + 2x) = 81x 4x² + (9 - 4x²) = 81x 4x² + 9 - 4x² = 81x

Step 2: Simplify the equation by combining like terms. 9 = 81x

Step 3: Divide both sides of the equation by 81 to solve for x. x = 9 / 81 x = 1 / 9

So, the solution to the equation 4x² + (3 - 2x)(3 + 2x) = 81x is x = 1/9.
