Document Summary

Topic 1: factoring out greatest common factor, if exists always try first ! Topic 2: factoring quadratic (degree 2): ax 2 + bx + c. Topic 3: factoring cubic (degree 3): ax 3 + bx2 + cx + d. Method #1: standard rules - shortcuts (if a rule applies) Topic #5: more about zeros / roots method works for all polynomials ! Rational roots theorem (to find zeros / roots) 7--- f i n d m o r e r e s o u r c e s a t o n e c l a s s. 1jp+e . j- : -j l-i" - i * x]: (--) l.
