Question

( x^{2}+a x+b c=0 quad 4 x^{2}+b x+c a=0 )
( alpha, beta )
( a+B=-a rightarrow(3) quad a, gamma )
( alpha beta=b c rightarrow mathbb{O} quad alpha+gamma=-b rightarrow theta )
( operatorname{eq} frac{theta}{e q}=>frac{beta}{gamma}=frac{b}{a} )
( e q(s)-e q theta quad beta=frac{b gamma}{a} )
( beta-gamma=b-a )

# 0.27 If equation x + ax + bc = 0 and x + bx + ca = 0 have one root common then their remaining roots are (A) a b (B) b, a (C) b, c (D) e, a
