Answer 3

The discriminant (denoted as Δ) is a term used in quadratic equations to determine the nature of their solutions. In the quadratic equation ax² + bx + c = 0, the discriminant is given by the expression b² - 4ac.

For the equation 9x² - 4 = 0, let's determine the discriminant.

Here, a = 9, b = 0, and c = -4. Plugging these values into the discriminant formula, we have:

Δ = b² - 4ac = 0² - 4 * 9 * (-4) = 0 - (-144) = 0 + 144 = 144

Therefore, the discriminant for the equation 9x² - 4 = 0 is 144.
