1. What type of solutions would we get from the quadratic equation
f (x)= 3x2 + 8x + 2?

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

The number if marbles of different colors stored in a hat is listed below: 4 red marbles 10 green marbles 7 blue marbles. without looking in the hat, dan takes out a marble at random. he replaces the marble and then takes out another marble from the hat. what is the probability that dan takes out a blue marble in both draws?
