-х^2-х^2+х+2х^2+4х=-1-3

5х=-4

х=-(4/5)

х=-0,8

Answer 2

To solve the equation -x^2 + 4x + 3 = x^2 - x - (1 + 2x^2), you can start by simplifying and rearranging the terms to isolate the variable x on one side of the equation. Here's the step-by-step solution:

1. Start with the given equation: -x^2 + 4x + 3 = x^2 - x - (1 + 2x^2)

2. Distribute the negative sign on the right side of the equation: -x^2 + 4x + 3 = x^2 - x - 1 - 2x^2

3. Group like terms on each side: (-x^2 + 4x + 3) = (x^2 - 2x^2) - x - 1

4. Combine like terms on each side of the equation: -x^2 + 4x + 3 = -x^2 - x - 1

5. Now, let's move all the terms involving x to one side of the equation by adding x^2 and x to both sides: -x^2 + x^2 + 4x + x - 3 = -x^2 - x^2 - x - 1 - 3

6. Simplify further: 5x - 3 = -2x - 4

7. Add 2x to both sides to collect the x terms on the left side: 5x + 2x - 3 = -4

8. Combine like terms on the left side: 7x - 3 = -4

9. Now, add 3 to both sides to isolate the 7x term: 7x - 3 + 3 = -4 + 3

10. Simplify: 7x = -1

11. Finally, divide both sides by 7 to solve for x: 7x/7 = -1/7

12. The solution is: x = -1/7

So, the solution to the equation is x = -1/7.
