Given:
The equation is
To find:
The number of roots and discriminant of the given equation.
Solution:
We have,
The highest degree of given equation is 2. So, the number of roots is also 2.
It can be written as
Here, .
Discriminant of the given equation is
Since discriminant is , which is greater than 0, therefore, the given equation has two distinct real roots.
The answer is 22 because in order to divide fractions (in this case we would have 11 as a fraction), you need to multiply one fraction by the reciprocal of the other fraction (the flipped form of a fraction).
To find this, we would do *
.
This would come to be , and when simplified by dividing the numerator and denominator by 9, you get 22.
