Deflate the polynomial. For the second root, the sequence e x is: 0, 1.1429652033882083, 1.5033931418129303, 1.5207705987491464, 1.5207734254923810. Deflate the polynomial again. The quadratic equation gives the other two roots are 2.3315151158001272 and2.4320989567191658. (2) (Matrix Operations) P. 148 #1, 2, 3, 4, 5, 6, 7, 8, 9 1 a. 6 1 8 6 1 6 1 b.
