The discriminant of the quadratic equation is:
24
Step-by-step explanation:
We know that for any quadratic equation of the type:
The discriminant of a quadratic function is denoted by D and is calculated by the formula:
Now here we are given a quadratic equation as:
which is written as:
i.e. we have: a=5 , b=2 and c= -1
Now, the discriminant is calculated as:
Hence, the discriminant is:
24
