  9. Objective • To solve polynomial equations using any method

  10. Solving POLYNOMIAL Send equation with “u” back through process STANDARD FORM Put any non-linear factors back through TAKE OUT GCF YES Put (a2+ ab + b2) (a2 – ab + b2) back through DIFF OF SQUARES? (a + b)(a – b) and find zeroes YES NO QUADRATIC? NO (a + b)(a2 – ab + b2) (a - b)(a2 + ab + b2) and find zeroes YES YES CAN YOU FIND: m*n = ac m + n = b If a = 1: (x + m)(x + n) If a > 1: split middle, find factors and then find zeroes NO SUM/DIFF OF CUBES? NO ALWAYS YES Substitute u, factor to find zeroes Split middle, find factors and then find zeroes QUADRATIC FORMULA NO GROUPING? There are x - ints YES GRAPH & FIND X - INTERCEPTS x – intercepts are real solutions or zeroes NO YES There are no x - ints CAN YOU USE: u = xn GRAPHING CALC?
