Concept explainers
To compute the discriminant of the equation and determine the number of real solutions.
Answer to Problem 53SGR
The discriminant is -4 . Since it is negative, there are no real solutions.
Explanation of Solution
Given information :
The equation is
Formula used :
Discriminant is found out using the formula
The solutions can be determined by:
If discriminant is negative, then there are no real solutions.
If discriminant is zero, then there is 1 real solution.
If discriminant is positive, then there are 2 real solutions.
Calculation :
Given equation.
Hence,
Putting the values in the formula.
Simplifying
This is the discriminant. Since it is negative, there are no real solutions.
