Question

Dou 3 x 2 + 5x+ 2 = 0​

Answer 1

Ответ:

$x = - \frac{8}{5}$

Answer 2

To solve the equation 3x^2 + 5x + 2 = 0, you can use the quadratic formula, which is given by:

x = (-b ± √(b² - 4ac)) / (2a)

In this equation, a = 3, b = 5, and c = 2. Plug these values into the quadratic formula:

x = (-5 ± √(5² - 4 * 3 * 2)) / (2 * 3)

Now, calculate the values under the square root:

x = (-5 ± √(25 - 24)) / 6 x = (-5 ± √1) / 6

Now, calculate the square root of 1:

x = (-5 ± 1) / 6

Now, you have two possible solutions:

1. x = (-5 + 1) / 6 = -4/6 = -2/3
2. x = (-5 - 1) / 6 = -6/6 = -1

So, the solutions to the equation 3x^2 + 5x + 2 = 0 are:

1. x = -2/3
2. x = -1
