Determine the nature of the roots of 3x² + (4)x + (4) = 0 using the discriminant.
Explanation
Explanation
The discriminant is D = b² - 4ac = (4)² - 4(3)(4) = 16 - 48 = -32. Since D 0, the equation has no real roots.
PRO TIP
Re-check your working by substituting the answer back into the original question.
