You can put this solution on YOUR website! ez enough, but check if i do sumthin wrong
4b(4b)-8b-5=0 now factor adds up to -8 and multiplies to -80. -10*8. there fore the equation yields . has 8b in common, -10b-5 has -5 in common. our new equation, factored once, is
8b(2b+1)-5(2b+1)
likes attract and: (8b-5)(2b+1)=0 thence one of the two (...) must equal zero, we don't know which, thence X=-.5 or 5/8
im me 4 questions.
