Question

F(x) = x2 – 3x + 18

Answer 1

Answer:

Step-by-step explanation:

The discriminant is part of the quadratic formula.  If the value of the discriminant is less than 0, you have 2 imaginary solutions; if the discriminant is equal to 0, you have 1 real solution; if the discriminant is greater than 0, you have 2 real solutions.

The discriminant is $b^2-4ac$, which for us, looks like this:

$(-3)^2-4(1)(18)$ which simplifies to -63.  That means that the solutions are imaginary...not real at all.  So in answer to your question, there are no real zeros at all.

Answer 2

Answer:

-63 and 0
