Question

1) for a > o, b>o, both roots of the equation ax^2+bx+c=0 are a) real and -ve b) have -ve real -ve real part c) real and +ve d) cannot be determined

2) if one roots is 3times of other ax^2+bx+c=0 (a not equal 0) , then 16 ac= a) 2b^2 b) 3b^2 c) 4b^2 d) b^2

3) let alpha,bita be the roots of the equation (x-a) (x-b)=c,c is not equal 0,then the roots of the equation (x-alpha) (x-bita) +c=0 are a) a,c b) b,c c) a,b d) a+c,b+c ​
