Document Summary
Fall 2005, mathematics 100 final exam solutions: marinescu and b. ong. 1. (a) (4 points) 6x2 x 1 = 0. Thus x = 1: if they factored correctly, but didn"t solve for x, give 2 points, if they factored incorrectly 0 points. (b) (4 points) 6x2 x 1 0. 6x2 x 1 = (3x + 1)(2x 1) 0. {x 1: award one point for realizing that keeping the factored form is useful. (i. e. their solution has 1. 3 oating around): if they had a mistake in (a), and carried it thru to here, don"t penalize them again, award three points for the correct solution. They may express their solution in any fashion, provided it is accurate: if they have extraneous expressions (or con icting answers, e. g. the number line solution is correct, but they say 1. Just circle the incorrect expression, incase they come in to look at their exams. 3 (c) (5 points) 6e2x ex 1 = 0.
