Question

9х в квадрате - 9х+2=0

Answer 1

1. 9x^2-3x-6x+2=0
2.3x(3x-1)-2(3x-1x)=0
3.(3x-1)(3x-2)=0
4. 3x-1=0
x=1/3
3x-2=0
x=2/3
5.x1= 1/3
x2=2/3

Answer 2

To solve the quadratic equation 9x^2 - 9x + 2 = 0, we can use the quadratic formula:

The quadratic formula is given by:

x = (-b ± √(b^2 - 4ac)) / 2a

where, in our equation, a = 9, b = -9, and c = 2.

Now, plug these values into the quadratic formula:

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

x = (9 ± √(81 - 72)) / 18

x = (9 ± √9) / 18

Now, we have two possible solutions:

1. x = (9 + 3) / 18 x = 12 / 18 x = 2/3

2. x = (9 - 3) / 18 x = 6 / 18 x = 1/3

So, the solutions to the equation are x = 2/3 and x = 1/3.
