The second solution is from two seconds before launch, which doesn t make sense in this context. (It makes sense on the graph, because the line crosses the x-axis at –2, but negative time won t work in this word problem.) So t = –2 is an extraneous solution, and I ll ignore. Solution of exercise 1. Determine the quadratic equation whose solutions are: 3 and −2. S = 3 − 2 = 1. P = 3 · 2 = 6. x² − x + 6 = 0 . Solution of exercise 2. Factor: Solution of exercise 3. Determine the value of k so that the two roots of the equation x² − kx + 36 = 0 are equal.
The second solution is from two seconds before launch, which doesn t make sense in this context. (It makes sense on the graph, because the line crosses the x-axis at -2, but negative time won t work in this word problem.) So t = -2 is an extraneous solution, and I ll ignore.
