Show that the equation (k + 1)x2 − 2x − k = 0 has a solution for all values of k
Question
Solution 1
To show that the equation (k + 1)x^2 - 2x - k = 0 has a solution for all values of k, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the solutions for x can be found using the formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
