Determine the nature of the roots of 3x² + (-2)x + (-6) = 0 using the discriminant.
Explanation
Explanation
The discriminant is D = b² - 4ac = (-2)² - 4(3)(-6) = 4 - -72 = 76. Since D > 0, the equation has two distinct real roots.
PRO TIP
Re-check your working by substituting the answer back into the original question.
