Answer:
-56
Explanation:
ax^2 + bx + c = 0 is the discriminant of the quadratic equation
3 - 4x= -6x^2
to
-6x^2 + 4x -3 = 0
We know that:
a = -6
b = 4
c = -3
Substitute in the formula of discriminant (b^2 - 4ac):
= 4^2 - 4 * (-6) * (-3)
= 16 - 4 * 18
= -56
Answer:
Explanation:
It certainly isn't the last one. A theory is close to a guess. It fits all the known facts, but there is usually something missing. If someone figures out what is missing, usually by experiment, then the theory become a fact.
The rest of them (1 2 an 3) can all be true. 3 is the least viable. You have to be able to come up with a counter example to reject a theory.
I'm not sure about 2. New phenomena can still be part of current theories. Reluctantly, I wouldn't choose 2 because
1 is the best answer of a very poor lot. Do not be surprised if you use it, that it turns out to be wrong.
