In a quadratic equation of the form (ax^2 + bx + c), the discriminant is equal to (b^2 - 4ac).
So for the first question it would be
4^2 - 4*(6*-2) = 64
Second question (-7)^2 - 4*(9*5) = -131
You can do the rest.

Answer:
777592000
Step-by-step explanation:
6 times 10 = 60 to the power of 5 = 60x60x60x60x60 = 777600000
2 times 10 = 20 to the power of 3 = 20x20x20 = 8000
777600000 - 8000 = 777592000
Answer:
2) 7/-8
Step-by-step explanation:
7/-8 because there is one negative meaning that the whole fraction will be negative. If there were two negatives, or none, it would be positive. The original fraction, -7/8, is a negative. Also, the actual numbers are equivalent as well, 7/8 and 7/8.
