Best ResponseYou've already chosen the best response.0d=1/2 and d=3 This is the solution: Factor the equation 2d^2+5d3=0 into the following: (2d1)(d+3)=0 2d1=0 2d=1 d=1/2 d+3=0 d=3 Since there are two factors involved (2d1) and (d+3), then there are two solutions to the original equation. You can check these two solutions d=1/2 and d=3 by substituting first d=1/2 into the original equation and you will get zero; and then you can substitute the other value d=3 into the original equation and again you will get zero.
