Question

(х+3)(х-2)-(х-4)(х-1)=3х​

Answer 1

Ответ:

х=2,5

Пошаговое объяснение:

(х+3)(х-2)-(х-4)(х-1)=3х​

х²-2х+3х-6-х²+х+5х-4-3х=0

4х-10=0

4х=10

х=10/4

х=2,5

Answer 2

To solve the equation (x + 3)(x - 2) - (x - 4)(x - 1) = 3x, you can follow these steps:

1. Expand the expressions on both sides of the equation:

   (x + 3)(x - 2) - (x - 4)(x - 1) = 3x

   Expand the left side:

   (x^2 - 2x + 3x - 6) - (x^2 - x - 4x + 4) = 3x

2. Simplify further:

   (x^2 + x - 6) - (x^2 - 5x + 4) = 3x

3. Distribute the negative sign on the second term within the parentheses:

   x^2 + x - 6 - x^2 + 5x - 4 = 3x

4. Now, combine like terms on both sides of the equation:

   (x^2 - x^2) + (x + 5x) + (-6 - 4) = 3x

   6x - 10 = 3x

5. Subtract 3x from both sides to isolate x:

   6x - 3x - 10 = 3x - 3x

   3x - 10 = 0

6. Add 10 to both sides:

   3x - 10 + 10 = 0 + 10

   3x = 10

7. Finally, divide both sides by 3 to solve for x:

   (3x)/3 = 10/3

   x = 10/3

So, the solution to the equation is:

x = 10/3
