i.
To state: The value of c that will give two real solutions in the equation
The resultant value is
Given information:
The given equation is
Explanation:
Consider the given equation:
Compare the given equation with
Then the values are
The discriminate of the quadratic equation is:
For two real solutions D must greater than 0,
Add 4c on both sides,
Divide both sides by 4,
Therefore, for
ii.
To state: The value of c that will give two imaginary solutions in the equation
The resultant value is
Given information:
The given equation is
Explanation:
For two imaginary solutions D must less than 0,
Add 4c on both sides,
Divide both sides by 4,
Therefore, for
iii.
To state: The value of c that will give only one real solution in the equation
The resultant value is
Given information:
The given equation is
Explanation:
For only one real solutions D must be equal to 0,
Add 4c on both sides,
Divide both sides by 4,
Therefore, for
