are my signs wrong? or was I not supposed to take the 8 out?

OpenStudy (anonymous):

Its (8v-1)(4v-1).

OpenStudy (anonymous):

what did I do wrong?

OpenStudy (anonymous):

32v²-12v+1. Add up to -12 are -4 and -8. Multiply to 32. Check. Then plug in. 32v²-8v-4v+1. Take common. 8v(4v-1)-1(4v-1)= (8v-1)(4v-1).
