Explanation of Solution
Given information:
The equation:
Formula used:
Discriminant formula:
The discriminant D of a quadratic equation
Discriminant conditions:
If
If
If
Calculation:
The given equation is
To find the discriminant of the above equation, use the discriminant formula
Substitute
Since, the discriminant of the given equation is greater than 0;
So, the equation has two unequal and real solutions that is, the equation has two real solutions.
Hence, the required discriminant of the equation is 40 and the equation has two real solutions.
