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.
21 is the right answer goodluck
Answer:
We know that ,
Number of zeroes in a polynomial = degree of the polynomial
( degree of polynomial = the highest power in the polynomial )
therefore ,
