Step-by-step explanation:
discriminant must be minus cause the graph doesn't cross the x-axis .in other words it doesn't have an answer.plus , the "a" of the equation is minus too.
Answer:
A)
Step-by-step explanation:
1) To answer this question, we must remember what this discriminant stands for:
2) We must plug in this discriminant, in the square root of Quadratic Formula, to find its roots, i.e.:
The discriminant is a radicand.
3) The graph above shows us no Real roots for this equation then we have roots ∈ Complex Numbers, in other words:
4) So, it's A.
Answer:
Step-by-step explanation:
Given to ask the Teacher Write out the form of the partial fraction decomposition of the function
It is not necessary to find the coefficients
For decomposition of partial fractions the necessary condition is that the denominator should be in a position to be factored into atleast two factors.
Then only partial fraction is possible otherwise not.
Here
a)
Denominator =
So this can be resolved into partial fractions as
b) Here given
But denominator cannot be factored
So cannot be decomposed into partial fraction
