Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.

Answer:
-1/8 > x
Step-by-step explanation:
Rewrite the equation to -1 > 8x, so -1/8 > x
Dot -1/8 on the number line, and everything on the left of that point( if right is positive ) is x .
