Determine the nature of the roots of 3x² + (3)x + (5) = 0 using the discriminant.
Explanation
Explanation
The discriminant is D = b² - 4ac = (3)² - 4(3)(5) = 9 - 60 = -51. Since D 0, the equation has no real roots.
PRO TIP
Re-check your working by substituting the answer back into the original question.
