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.
