Ginny factored 6x2 – 31x – 30 as shown: ac = –180 and b = 31 36(–5) = –180 and 36 + (–5) = 31 6x2 + 36x – 5x – 30 6x(x + 6) – 5(x + 6) (x + 6)(6x – 5) Determine if Ginny factored correctly. If not, explain where she made an error. Ginny made a mistake in step 1 when she identified b = 31. It should be b = –31. Ginny was correct until step 3 when she used 36 and –5 as the coefficients of x. Ginny was correct until step 4 when she incorrectly factored the GCF from 5x – 30. Ginny factored the trinomial correctly.
