Number of Real and Non-Real Solutions By the Zeros Theo- rem, every nth-degree polynomial equation has exactly n solutions (including possibly some that are repeated). Some of these may be real, and some may be non-real. Use a graphing device to determine how many real and non-real solutions each equation has. (a) x - 2x - 11x + 12x = 0 (b) x* – 2r - 11x2 + 12x- 5 = 0 (c) x* - 2r – 11x? + 12x + 40 = 0 |
