SUMMARY
The discussion centers on solving the quadratic equation 3t² + 7t - 5 = 0 using the quadratic formula. The user initially calculated the roots as t = -4.39 and t = -9.61, but later realized a mistake in their calculations. The correct roots, as indicated by the tutor's answer book, are t = 0.573 and t = -2.907. The error stemmed from miscalculating the denominator in the quadratic formula, specifically the term 2(3), which should equal 6, not 4.
