Answer: -16
Step-by-step explanation:
-3 is less than -2 so use the first one
Plug into equation
5(-3)-1
-15-1= -16
Answer:
I think the answer is 0
Step-by-step explanation:
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.
