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.
