Case 1: Parabola crosses the x-axis twice → we obtain two intersections, 2 solutions
Case 2: Parabola crosses the x-axis once → we obtain one intersection, 1 solution
Case 3: Parabola does not cross the x-axis → we obtain zero intersections, no (real) solution
Question: discuss the relationship between the discriminant of a quadratic polynomial and the quantity of real roots it possesses. Think of an example, where you take the standard form of a quadratic equation and use the quadratic formula to find the solutions (if any). Indicate which case your example falls into (one of three cases listed above).

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
