Answer:

[tex]3t^{2} + 7t - 2 > 0[/tex]

Explanation:

A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign. The solutions to quadratic inequality always give two roots. The nature of the roots may differ and can be determined by discriminant (b2 – 4ac).

In order for an equation to be called a quadratic inequality, it should have an inequality sign (< or >). The highest exponent should also be 2. If the equation follows the  [tex]ax^{2} + bx + c < 0[/tex] format, A should not be equal to 0.

Only option C satisfies what a quadratic inequality is since it has an inequality sign and it follows the [tex]ax^{2} + bx + c < 0[/tex] format.
