To find the discriminant of the quadratic equation -9x^2 - 7x - 7=0, we can use the formula:
Discriminant = b^2 - 4ac
In this equation, a=-9, b=-7, and c=-7. Let's plug in the values:
Discriminant = (-7)^2 - 4(-9)(-7)
= 49 - 252
= -203
So, the discriminant of the quadratic equation -9x^2 - 7x - 7=0 is -203. Therefore, the correct answer is minus, 203 (-203).
