WebbNow simplify. It is almost always easier to factor rather than expand when simplifying. You can use that to help you factor. that you want a (k+1) (k+2) (2k+3) in the final form. We see right now that there is a (k+1) that is common to both of those, so let's begin by factoring it out. Sk+1= ( k + 1) [ k ( 2k + 1 ) + 6 ( k + 1 ) ] / 6 Webbthen simplify, substitute then simplify, repeatedly, addressing just one side at a time until both sides of the equality agree. 3. [3 pts] Try #28 again: Prove that F2 k+1 −F 2 k −F2 k−1 = 2FkFk−1 for all integers k ≥ 1. F 2 k+1 −F 2 k −Fk−1 = 2? F kFk−1 (Fk +Fk−1) 2 − F2 k −F 2 k−1 =? 00 F2 k +2FkFk−1 +F 2 k−1 − F 2
