Answer 2

To solve the equation (3x - 1)^2 = 4 - 12x, we can start by expanding the squared term on the left side:

(3x - 1)^2 = (3x - 1)(3x - 1) = 9x^2 - 6x + 1

Now, the equation becomes:

9x^2 - 6x + 1 = 4 - 12x

Let's simplify the equation further by bringing all the terms to one side:

9x^2 - 6x + 12x - 1 - 4 = 0

Rearranging the terms:

9x^2 + 6x - 5 = 0

This is now a quadratic equation in standard form. To solve it, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 9, b = 6, and c = -5. Substituting these values into the quadratic formula:

x = (-(6) ± √((6)^2 - 4(9)(-5))) / (2(9))

Simplifying:

x = (-6 ± √(36 + 180)) / 18 x = (-6 ± √216) / 18 x = (-6 ± 6√6) / 18

We can simplify this further by factoring out a common factor of 6 in the numerator and denominator:

x = (6(-1 ± √6)) / (6(3)) x = (-1 ± √6) / 3

Therefore, the solutions to the equation (3x - 1)^2 = 4 - 12x are:

x = (-1 + √6) / 3 x = (-1 - √6) / 3
