Question

3х²+3х-3х²+1=3х²+х-2​

Answer 1

3х^2+3x-3x^2+1-3x^2-x+2=0

-3x^2+2x+3=0

 

Найдем дискриминант квадратного уравнения:

D = b2 - 4ac = 22 - 4·(-3)·3 = 4 + 36 = 40

Так как дискриминант больше нуля то, квадратное уравнение имеет два действительных корня:

x1 =   -2 - √40 2·(-3)  =   1/3  +   1/3 √10 ≈ 1.3874258867227933

x2 =   -2 + √40 2·(-3)  =   1/3  -   1/3 √10 ≈ -0.7207592200561265

Answer 2

To solve the equation 3x² + 3x - 3x² + 1 = 3x² + x - 2, you can simplify and solve for x. Here's the step-by-step solution:

1. Start by simplifying both sides of the equation by combining like terms:

   3x² - 3x² + 3x - 1 = 3x² - 3x² + x - 2

   3x - 1 = x - 2

2. Now, isolate the variable x on one side of the equation. You can do this by subtracting x from both sides:

   3x - 1 - x = x - 2 - x

   2x - 1 = -2

3. Next, add 1 to both sides to further isolate x:

   2x - 1 + 1 = -2 + 1

   2x = -1

4. Finally, divide both sides by 2 to solve for x:

   (2x) / 2 = (-1) / 2

   x = -1/2

So, the solution to the equation is x = -1/2.
