Question

X²-4,5x+4,5=0кв.уравнение

Answer 1

x^2-4,5x+4,5=0

D= -4,5^2-4*1*4,5

D= 20,25-18

D= 2,25

x= 4,5±√2,25/2

x1= (4,5-1,5)/2

x1= 1

x2= (4,5+1,5)/2

x2= 3

Ответ: x1= 1; x2=3

Answer 2

To clarify, I assume you have the quadratic equation:

x² - 4.5x + 4.5 = 0

To solve this quadratic equation, you can use the quadratic formula:

For a quadratic equation of the form ax² + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b² - 4ac)) / 2a

In your case, a = 1, b = -4.5, and c = 4.5. Let's plug these values into the formula:

x = (4.5 ± √((-4.5)² - 4 * 1 * 4.5)) / 2 * 1 x = (4.5 ± √(20.25 - 18)) / 2 x = (4.5 ± √2.25) / 2 x = (4.5 ± 1.5) / 2

Now, we have two possible solutions:

1. x = (4.5 + 1.5) / 2 x = 6 / 2 x = 3

2. x = (4.5 - 1.5) / 2 x = 3 / 2 x = 1.5

So, the solutions to the quadratic equation are x = 3 and x = 1.5.
