To solve the quadratic equation 3x^2 + 14x + 15 = 0, you can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a), where a = 3, b = 14, and c = 15. Plugging in these values, you get x = (-14 ± √(14^2 - 4(3)(15))) / (2*3). Simplifying further, you get x = (-14 ± √(196 - 180)) / 6, which becomes x = (-14 ± √16) / 6. This simplifies to x = (-14 ± 4) / 6. Therefore, the solutions are x = (-14 + 4) / 6 = -10 / 6 = -5/3 and x = (-14 - 4) / 6 = -18 / 6 = -3. So, the solutions are x = -5/3 and x = -3.
