Question

\[ax^2 + b \left[ x \right] + c =0\] the sum of roots is?

Answer 1

why is that x in brackets?
is it supposed to be mod ?

Answer 2

yes it is mod

Answer 3

matlab, for x>0
\(ax^2 + bx + c =0\)

and, for x<0
\(ax^2 +bx + c=0\)


so for the first one, sum of roots = -b/a
and for the second one, b/a

Answer 4

thxx so the answer is 0

Answer 5

0 ?? nops..it will have 2 ans for 2 diff cases..

Answer 6

Nope, they are just two different cases defining equation.
