Answer:
A.
Explanation:
A quadratic inequality looks like a quadratic equation, but with signs
<, >, ≤, or ≥
instead of sign =
You are given one equation (the first one, because the sign is =) and two inequalities (the last two beacause the signs are < and > respectively).
Thus, correct option is A,
is not a quadratic inequality (it is a quadratic equation)
