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:
= 6
Step-by-step explanation:
in the third step, they did 2 x -12 and got 24. It should’ve been -24 since it was a positive times a negative. It shouldve been
-24 - (-30)
-24 + 30
= 6
