Question

2х^2-7х+3=0 плиииизззз9​

Answer 1

Ответ:

x1=0.5 x2=3

Пошаговое объяснение:

a=2                     D=(-7)^2-4*2*3=49-24=25

b=-7                     x1.2= -b+-Корень из D/2a

c=3                       7+-5/4

                            x1=2/4= 1/2 =0.5

                           x2=12/4 = 3

Answer 2

To solve the quadratic equation 2x^2 - 7x + 3 = 0, you can use the quadratic formula, which is:

x = (-b ± √(b^2 - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

For the equation 2x^2 - 7x + 3 = 0:

a = 2 b = -7 c = 3

Now, plug these values into the quadratic formula:

x = (7 ± √((-7)^2 - 4 * 2 * 3)) / 2 * 2

x = (7 ± √(49 - 24)) / 4

x = (7 ± √25) / 4

Now, calculate the two possible values of x:

1. x = (7 + √25) / 4 x = (7 + 5) / 4 x = 12 / 4 x = 3

2. x = (7 - √25) / 4 x = (7 - 5) / 4 x = 2 / 4 x = 1/2

So, the solutions to the equation 2x^2 - 7x + 3 = 0 are x = 3 and x = 1/2.
