"ALGEBRA QUESTION OF THE DAY"
For what values of 'm' is y = 0, if y = x2 + (2m + 1)x + m2 - 1? x is a real number.
For what values of 'm' is y = 0, if y = x2 + (2m + 1)x + m2 - 1? x is a real number.
since,this is a objective question so,need not to solve in detail for m<0 arbitraly a small value is chosen so,that max. term become 0.let,m=-1' then,eqn.will be y=x2-x=x(x-1)=0 or 1 i.e y=0 there are more method for this if interested contact me.
i think it cannot b possible bcoz there is a term x2 which does not have any coeff in terms of m
ReplyDeletethe answer is m=0
ReplyDeletei think the answer is m<0

for m<0 arbitraly a small value is chosen so,that max. term become 0.let,m=-1'
then,eqn.will be y=x2-x=x(x-1)=0 or 1 i.e y=0

hence, righat ans. is m<0
