In the denominator, factor out common factor, 6. This leaves: 2a(4b-1) -------- 6(1-4b) Now notice that the signs of 1 and 4b in the denoninator are reversed. So we will revise the last step and factor out -6 vice +6. 2a(4b-1) -------- -6(-1+4b) rewrite: 2a (4b-1) -------- (4b-1)cancels -6 (4b-1) -a --- 3 Hope this helps.
