Question

9x в квадрате -6x+1=0​

Answer 1

9х^2-6х+1=0

D=b^2-4ac

D=36-36

D=0

x=(6+0):9*2

x=1/3

Answer 2

Ответ:

9x^2-6x+1=0 Выделим полный квадрат двучлена, или разложим на множители с помощью формулы сокращ умножения  

(3x-1)^2=0  

3x-1=0  

3x=1  

x=1/3.  

ответ: 1/3

Answer 3

To solve the quadratic equation 9x^2 - 6x + 1 = 0, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the solutions for x can be found using the following formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In our case, a = 9, b = -6, and c = 1. Plugging these values into the formula, we get:

x = (6 ± √((-6)^2 - 4 * 9 * 1)) / 2 * 9 x = (6 ± √(36 - 36)) / 18 x = (6 ± √0) / 18

Since the discriminant (the value inside the square root) is 0, the equation will have one real and identical root:

x = (6 + 0) / 18 x = 6 / 18 x = 1/3

So, the solution to the equation is x = 1/3.
