Answer Key for the Root Finding Handout

1.) [Graphics:Images/index_gr_1.gif]

[Graphics:Images/index_gr_2.gif] can be factored as [Graphics:Images/index_gr_3.gif].  So, [Graphics:Images/index_gr_4.gif] has roots at [Graphics:Images/index_gr_5.gif]

2.) [Graphics:Images/index_gr_6.gif]

[Graphics:Images/index_gr_7.gif] can be factored as [Graphics:Images/index_gr_8.gif].  So, [Graphics:Images/index_gr_9.gif] has roots at [Graphics:Images/index_gr_10.gif]

3.) [Graphics:Images/index_gr_11.gif]

[Graphics:Images/index_gr_12.gif] can be factored as [Graphics:Images/index_gr_13.gif].  So, [Graphics:Images/index_gr_14.gif] has roots at [Graphics:Images/index_gr_15.gif]

4.) [Graphics:Images/index_gr_16.gif]

[Graphics:Images/index_gr_17.gif] can be factored as [Graphics:Images/index_gr_18.gif].  So, [Graphics:Images/index_gr_19.gif] has roots at [Graphics:Images/index_gr_20.gif]

5.) [Graphics:Images/index_gr_21.gif]

[Graphics:Images/index_gr_22.gif] can be factored as [Graphics:Images/index_gr_23.gif].  So, [Graphics:Images/index_gr_24.gif] has roots at [Graphics:Images/index_gr_25.gif]

6.) [Graphics:Images/index_gr_26.gif]

[Graphics:Images/index_gr_27.gif] can be factored as [Graphics:Images/index_gr_28.gif].  So, [Graphics:Images/index_gr_29.gif] has roots at [Graphics:Images/index_gr_30.gif]
