Question

3хво второй степени минус 8х плюс 4 равно нулю

Answer 1

3х^2-8х+4=0
D = 64-48=16 = 4^2
x1 = (8+4)/6 = 2
x2 = (8-4)/6 = 2/3

Answer 2

To solve the quadratic equation, you can set it to zero and then apply the quadratic formula. The equation you provided is:

3x^2 - 8x + 4 = 0

Now, you can use the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b^2 - 4ac)) / 2a

For the given equation, a = 3, b = -8, and c = 4. Now, plug these values into the formula:

x = (8 ± √((-8)^2 - 4 * 3 * 4)) / 2 * 3 x = (8 ± √(64 - 48)) / 6 x = (8 ± √16) / 6 x = (8 ± 4) / 6

Now, we have two possible solutions:

1. x = (8 + 4) / 6 x = 12 / 6 x = 2

2. x = (8 - 4) / 6 x = 4 / 6 x = 2/3

So, the solutions for the equation 3x^2 - 8x + 4 = 0 are x = 2 and x = 2/3.
