Question

If x=(_1), then what is the value
of x2 + 2x+1 l l
​

Answer 1

Answer:

This question is undoable because they're doesn't exist a solution for (x+2)/x=1 as I will show here:

(x+2)/x=1

Multiply both sides of the equation to get rid of the fraction this will give us

(x+2)=x

This equation doesnt make mathematical sense as a variable x cannot be of equal value as the statement x+2.

Therefore x doesn't have any value, even if you check Wolphram Alpha it will tell you there's no solution. Since there is no solution we can't plug x into the 2nd equation.

Solving the given equation for x, we find two complex roots to the quadratic equation x^2 - x + 2 = 0:

x = (1 +/- sqrt(7)*i)/2

And

x^2 = (-3 +/- sqrt(7)*i)/2

We can simplify x^2 + x + 2*(1 - x)/x^2 by replacing x with x^2 + 2 to get:

2*(x^2 - 1/x^2)

Substituting the known values for x^2 we get:

(-9 +/- 5*sqrt(7)*i)/4
