If ax^(2) + bx + c = 0 , a , b, c in R has no real roots, and if c lt 0, the which of the following is ture ? (a) a lt 0 (b) a + b + c gt 0 (c) a +b +c lt 0

Given that ax^(2)+bx+c=0 has no real roots and a+b+c 0 d.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 the equation f(x)= ax^2+bx+c=0 has no real root, then (a+b+c)c is (A) =0 (B) gt0 (C) lt0 (D) not real

If the equation ax^(2)+25x-3c=0 has non real roots and (3c)/4lt(a+b), then c is always (A) Negative (B) 0(C) Non-negative (D) zero

If the roots of equation ax^(2)+bx+c=0;(a,b,c in R and a!=0) are non-real and a+c>b. Then

If the equation |x^(2)+bx+c|=k has four real roots,then A.b^(2)-4c>0 and 0 0 and k>(4c-b^(2))/(4) D.none of these

If ax^(2)+(b-c)x+a-b-c=0 has unequal real roots for all c in R,then
