2x^2+9x+10=0
         2
x^2+9/2x=-5
x^2+9/2x+[1/2(9/2)]^2=-5+[1/2(9/2)]^2
x^2+9/2x+81/16=-5+81/16
(x+9/4)(x+9/4)=1/16
sqrt of (x+9/4)^2= sqrt of 1/16
x+9/4=sqrt 1/16
for the postive value of x

x=1/16-9/4
  =-35/16
you can get the other LOWEST TERM but im not sure for what can be may answer. for that term

for the negative value of x
x=-1/16-9/4
  =-37/16
and also for this one,,,you can get the other  LOWEST TERM for it just try
hope it will help you ^_^
