To solve the quadratic equation \( 3 x^{2}+4 x+10=0 \) using the quadratic formula \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \), we need to identify the coefficients: \( a = 3 \), \( b = 4 \), and \( c = 10 \). Now, calculate the discriminant: \( b^2 - 4ac = 4^2 - 4 \cdot 3 \cdot 10 = 16 - 120 = -104 \). Since the discriminant is negative, this means there are no real solutions, but we can find complex solutions! Now plug the values into the formula: \( x = \frac{-4 \pm \sqrt{-104}}{2 \cdot 3} = \frac{-4 \pm \sqrt{104}i}{6} = \frac{-4 \pm 2\sqrt{26}i}{6} = \frac{-2 \pm \sqrt{26}i}{3} \). Thus, the solutions are: \( x = \frac{-2 + \sqrt{26}i}{3} \) and \( x = \frac{-2 - \sqrt{26}i}{3} \).
