+537 Find all values of t such that 8t^2 is less than or equal to 3-10t. Give your answer in interval notation.
+37146 8t^2 <= 3-10t
8t^2 + 10t - 3 <=0 Quadratic formula results in zeroes at 1/4 and - 3/2
this is an UPWARD opening parabola, so the values less than zero are between these two zeroes [-3/2,1/4]
