Нейросеть22 декабря 2023 07:14

To solve the equation x - 3x(1 - 12x) = 11 - (5 - 6x)(6x + 5), we can follow these steps:

  1. Simplify both sides of the equation: x - 3x + 36x^2 = 11 - (30x^2 - 11x + 30x - 25)

  2. Combine like terms: -2x + 36x^2 = 11 - 30x^2 + 1x - 30x + 25

  3. Simplify further: 36x^2 + 2x - 11x + 30x + 30x^2 = 11 + 25 - 30x^2 + 30x

  4. Combine like terms again: 66x^2 - 9x = 36 - 30x^2 + 30x

  5. Rearrange the equation to bring all terms to one side: 66x^2 - 9x - 36 + 30x^2 - 30x = 0

  6. Combine like terms: 96x^2 - 39x - 36 = 0

Now, this is a quadratic equation in the form of ax^2 + bx + c = 0.

To solve this quadratic equation, you can either factor it, complete the square, or use the quadratic formula.

Let's solve it using the quadratic formula:

  1. Apply the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a)

In our case, a = 96, b = -39, and c = -36.

x = (-(-39) ± √((-39)^2 - 4 * 96 * (-36))) / (2 * 96)

x = (39 ± √(1521 + 13824)) / 192

x = (39 ± √(15345)) / 192

  1. Simplify the square root: x = (39 ± √(3 * 5115)) / 192

x = (39 ± √(3) * √(5115)) / 192

x = (39 ± √(3) * 71.545) / 192

At this point, we have two possible solutions, one using the positive sign and one using the negative sign.

  1. Calculate the solutions: x1 = (39 + √(3) * 71.545) / 192 ≈ 0.226 x2 = (39 - √(3) * 71.545) / 192 ≈ -0.332

Therefore, the solutions to the equation x - 3x(1 - 12x) = 11 - (5 - 6x)(6x + 5) are approximately x1 ≈ 0.226 and x2 ≈ -0.332.

To solve the equation x - 3x(1 - 12x) = 11 - (5 - 6x)(6x + 5), we can follow these steps: 1. Simplify both sides of the equation: x - 3x + 36x^2 = 11 - (30x^2 - 11x + 30x - 25) 2. Combine like terms: -2x + 36x^2 = 11 - 30x^2 + 1x - 30x + 25 3. Simplify further: 36x^2 + 2x - 11x + 30x + 30x^2 = 11 + 25 - 30x^2 + 30x 4. Combine like terms again: 66x^2 - 9x = 36 - 30x^2 + 30x 5. Rearrange the equation to bring all terms to one side: 66x^2 - 9x - 36 + 30x^2 - 30x = 0 6. Combine like terms: 96x^2 - 39x - 36 = 0 Now, this is a quadratic equation in the form of ax^2 + bx + c = 0.
