What is the solution of the equation x + 2x-1 = 0

What is the solution of the equation x + 2x-1 = 0

Square of X + 2x-1 = 0
Can be organized into
x²+2x+1=2
So the recipe has to be
（x+1)²=2
So there is
X + 1 = radical 2 or x + 1 = - radical 2
So the solution is
X = - 1 + radical 5 or x = - 1 - radical 2

Equation: x + 2 / 2 X-2 + x square - 4 / 4 equals 1 how to solve?

[(x-2)/(x+2)]+[4/(x²-4)]=1[(x-2)²/(x+2)(x-2)]+[4/(x²-4)]=1[(x²-4x+4)/(x²-4)]+[4/(x²-4)]=1(x²-4x+4+4)/(x²-4)=1(x²-4x+8)/(x²-4)=1x²-4x+8=x²-4-...

If x = - 4, the function value is 9; if x = 6, the function value is 4. Find K and B

Substitution: 9 = - 4K + B (1)
4=6k+b (2)
4+5=9
The result is: 6K + B + 5 = - 4K + B
k=-1/2
b=7

The number of chickens in the factory is 25% more than that of ducks. How many percent less are ducks than that of chickens?

Let the number of ducks be 1, then the number of chickens is: 1 × (1 + 25%) = 1.25; (1.25-1) △ 1.25 = 0.25 △ 1.25 = 20%; answer: the number of ducks is 20% less than that of chickens
