The answer is x=3
if you divide each by -7 to isolate x, it’s equal to positive three because 2 negatives make a positive
The Correct Answer Is f(x)=2.5x+5
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.
