Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros?

The equation has one zero because the discriminant is 1.
The equation has one zero because the discriminant is a perfect square.
The equation has two zeros because the discriminant is greater than 0.
The equation has no zeros because the discriminant is not a perfect square.

Do you know how to find the dicrimenanet

manray · Answer

i have no clue man i failed this quiz 3 times now and i need some help[

will.h · Answer

to find the discriminant  we use $$b^2 - 4ac$$

manray · Answer

ok

will.h · Answer

okay so we have b = -7 and a = 3 and c = 4
so find the discriminant

manray · Answer

-49-48

manray · Answer

-97

will.h · Answer

so 97
that's the discriminant we don't care about the signs as you see it is not perfect square and not equal to 1 so the answer is C
make sense?
