If one ofthe roots of `x^2-bx + c = 0`; `b, cinQ` is `sqrt(7-4sqrt(3))` then- (A) `log_b c=0` (B) b+c=5 (C) log_cb=0 (D) bc =-4

If a=c=4b , then the roots of ax ^(2) + 4 bx + c =0 are

The equation ax^2+ bx + c=0, if one root is negative of the other, then: (A) a =0 (B) b = 0 (C) c = 0 (D) a = c

Theorem : The roots of ax^(2)+bx+c=0 are (-b pm sqrt(b^(2)-4ac))/(2a)

If the roots of x^(2)-bx+c=0 are two consecutive integers,then b^(2)-4c is 0(b)1 (c) 2 (d) none of these

If the roots of x^(2) - bx + c = 0 are two consecutive integral multiples of 5, then sqrt(b^(2) - 4c) is equal to ______

If a+b+c=0 then roots of the equation 3ax^(2)+4bx+5c=0 are

if one root of the quadratic equation ax^(2)+bx+c=0 is 3-4i then 31a+b+c=(A)0(B)2a(C)2b(D)2c

If b^2>4a c then roots of equation a x^4+b x^2+c=0 are all real and distinct if: (a) b 0 (b) b 0,c>0 (c) b>0,a>0,c>0 (d) b>0,a<0,c<0

If the roots of ax^2+bx+c=0 are real and equal then.......a) b^2-4aclt0 b) b^2-4ac=0 c) b^2-4acgt0 d) Cannot say

If 1/(2-sqrt(-2)) is one of the roots of ax^(2)+bx+c = 0 , where a,b, c are real, then what are the values of a,b,c respectively ?
