Answer 3

To solve the equation (1:2) 3 + (2x + 3) = 4(x - 6)(x + 6), follow these steps:

1. First, simplify both sides of the equation by applying the distributive property on the right side:

   3 + 2x + 3 = 4(x^2 - 36)

2. Combine like terms on the left side:

   6 + 2x = 4(x^2 - 36)

3. Distribute 4 on the right side:

   6 + 2x = 4x^2 - 144

4. Move all terms to one side of the equation to set it equal to zero. Subtract 6 and 2x from both sides:

   0 = 4x^2 - 2x - 144

5. Now, you have a quadratic equation in standard form. To solve it, you can use the quadratic formula:

   x = (-b ± √(b² - 4ac)) / (2a)

   In this equation, a = 4, b = -2, and c = -144.

   Plug these values into the quadratic formula:

   x = (-(-2) ± √((-2)² - 4 * 4 * (-144))) / (2 * 4)

6. Calculate the discriminant inside the square root:

   Discriminant = (-2)² - 4 * 4 * (-144) = 4 + 2304 = 2308

7. Now, plug the discriminant back into the quadratic formula:

   x = (2 ± √2308) / 8

8. You can simplify the square root if needed:

   x = (2 ± √(4 * 577)) / 8

   x = (2 ± 2√577) / 8

9. Finally, simplify further by factoring out a common factor of 2 in the numerator:

   x = (2/2) ± (2√577/8)

   x = 1 ± √577/4

So, the solutions to the equation are:

x = 1 + √577/4 x = 1 - √577/4
