Answer 1

2x²-9x+9=0
D=81-72=9
x=(9+3):4=3
x=(9-3):4=1,5
Ответ:1,5 и 3

Answer 2

$2 x^{2} -9x+9=0 \\ D=81-72=9 \\ \sqrt{D} =3 \\ x_{1} = \frac{9+3}{4} =3 \\ x_{2} = \frac{9-3}{4} =1.5$

Answer 3

Solving the Equation -2/9 = 5.6

To solve the equation -2/9 = 5.6, we can follow these steps:

1. Isolate the Variable: First, we need to isolate the variable (let's call it x) on one side of the equation. 2. Perform the Calculation: Then, we can perform the necessary calculations to find the value of x.

Let's proceed with solving the equation.

Solution

-2/9 = 5.6

To solve for x, we can isolate x on one side of the equation.

-2/9 = 5.6 -2 = 5.6 * 9 -2 = 50.4

As we can see, the equation -2/9 = 5.6 leads to the statement -2 = 50.4, which is not a valid equation. It seems there might be a mistake in the given equation, as it does not yield a meaningful solution.
