Answered by Damon
differs from what by 3 ?
do you mean the roots differ by 3 or something?
Answered by Collins
Yes the root
Answered by Damon
ok

x = [ -8+/- sqrt (64-16m) ]/8
so
(1/8) * 2 * sqrt (64-16 m) = 3

sqrt (64 - 16 m) = 12

64 - 16 m = 144

16 m = 80

m = 5

Answered by Collins
If
64-16m=144
-16m=80
m=-5? Can it be negative
