ANSWER
The discriminant is -3
EXPLANATION
The given quadratic equation is:
Comparing this equation to:
we have
a=1, b=3, and c=-6
The discriminant is calculated using the formula,
We substitute the values to get:
So firstly, we have to find the LCD, or lowest common denominator, of 9 and 7. To do this, list the multiples of 9 and 7 and the lowest multiple they share is going to be your LCD. In this case, the LCD of 9 and 7 is 63. Multiply x^2/9 by 7/7 and 2y/7 by 9/9:
Next, add the numerators together, and your answer will be:
