Question

determine so that p2 + 4p+8,p2+3p+6,3p2+4p+4 are three consecutive terms of an AP​

Answer 1

Answer:

∵ diagonals of a ║gm bisect each other

⇒ OA = OCOA=OC

⭢ OD = OBOD=OB

⭢∵OA = OC and AE = CF (Given)OA=OCandAE=CF(Given)

⭢ OA-AE = OC-CFOA−AE=OC−CF

⭢OE = OFOE=OF

∵BFDEBFDE is a quadrilateral whose diagonals bisect each other
