(Reuters) - Xerox Corp said on Tuesday it was planning to take the $33.5 billion (£26 billion) buyout bid directly to HP Inc shareholders after the personal computer maker refused to open its books for deal talks."We plan to engage directly with HP shareholders to solicit their support in urging the HP Board to do the right thing and pursue this compelling opportunity," Xerox said in a letter to HP's board.HP on Sunday rejected Xerox's $22 per share offer that involves $17 in cash and 0.137..
