Question

Hey can you please help me posted picture of question

Answer 1

The answer is B, 0.

The formula to find the discrimination of a quadratic equation is b^2 - 4ac.

Therefore, in order to find the answer of this question, you would create an equation like so:

12^2 - 4(4)(9)

144 - 16(9)
144-144
0

Hope this helps!

Answer 2

Discriminant of a quadratic function can be calculated as

Discriminant = b² - 4ac

where,
b = coefficient of x term = 12
a = coefficient of squared term = 4
c = constant = 9

So,

Discriminant = 144 - 4(4)(9) = 0

Therefore, the answer to this question is option B
