If `ax^(2)+bx+c=0`, `a ne 0`, `a`, `b`, `c in R` has distinct real roots in `(1,2)`, then `a` and `5a+2b+c` have

If ax^(2)+bx+c=0,a!=0,a,b,c in R has distinct real roots in (1,2) then a and 5a+2b+c hue (A) same sign (B opposite sign (C) not determined (D) none of these

If the equation ax^(2) + bx + c = 0, a,b, c, in R have non -real roots, then

If ax^(2)+bx+c=0 and cx^(2)+bx+a=0 (a, b, c in R) have a common non - real root, then

If ax^2 + bx + c = 0, a, b, c in R has no real zeros, and if a + b + c + lt 0, then

If ax^(2)+bx+c=0,a,b,c in R has no real zeros,and if c 0

If ax^(2)+bx+c = 0 has no real roots and a, b, c in R such that a + c gt 0 , then

If ax^(2)+bx+c = 0 has no real roots and a, b, c in R such that a + c gt 0 , then

If ax^2+bx+c =0 and cx^2+bx+a =0 (a,b,cinR) have a common non-real roots,then
