Determine if ginny factored correctly. if not, explain where she made an error.
1. ginny made a mistake in step 1 when she identified b = 31. it should be b = –31.
2. ginny was correct until step 3 when she used 36 and –5 as the coefficients of x.
3. ginny was correct until step 4 when she incorrectly factored the gcf from 5x – 30. 4.ginny factored the trinomial correctly.
