If \( abc0 \) and \( (a+b-2 c) x^{2}+(a+c-2 b) x+ \)
\( \mathrm{P} \) \( b+c-2 a=0 \) has one root in the interval \( (-1,0) \)

W then
(1) roots of \( a x^{2}+2 b x+c=0 \) are real and negative
(2) roots of \( c x^{2}+2 a x+b=0 \) are real and negative
(3) roots cf \( b x^{2}+2 c x+a=0 \) are real and negative
(4) none of these
