Unformatted text preview: with your approximate semester grade so far. The A’s started at about 200, and each letter is 25 points. Later I will include your HW, and will replace your lowest quiz score with your average MHW grade. 1) W = det ± x + 2 x 21 1 2 x ² = x 2 + 4 x + 1 6 = 0 . So , they are LI . 2) Your ﬁnal answer should be a basis of S ; a list of LI vectors in R 3 . Not a matrix, not a scalar, etc. This problem is very similar to HW 3.4.7 (factor out the a, b, c), but since the 3 vectors you get that way are LD, you must remove one (3 points if you didn’t). a + 2 b + c 2 a + 4 b a + 2 b = a 1 2 1 + b 2 4 2 + c 1 So, one basis for S is { [1 2 1] T , [1 0 0] T } . 3) TFTFT 4) See lectures and the text. 1...
