the answer for your question is y=−2
Answer:
zero, because the discriminant is negative
Step-by-step explanation:
By writing the quadratic formula, we have the discriminant written in the root as;
b^2-4ac
Now, given the expression, we can see that the discriminant here is -19
What this mean is that we have a negative discriminant
Hence, we can conclude that the roots are complex and as such, none of the roots are real
Answer:
Step-by-step explanation:
We are given the following in the question:
Percentage of vote required for constitutional amendment = 60%
p = 60% = 0.6
Hypothesis:
