If 1 is a twice repeated root of the equation `a x^3+b x^2+b x+d=0,t h e n` (a)`a=b=d` (b) `a+b=0` (c)`b+d=0` (d) `a=d`

If c lt a lt b lt d , then roots of the equation bx^(2)+(1-b(c+d)x+bcd-a=0

If x=1 is a common root of the equations a x^2+a x+3=0 and x^2+x+b=0 , then a b= (a) 3 (b) 3.5 (c) 6 (d) -3

If a and b are roots of the equation x^2+a x+b=0 , then a+b= (a) 1 (b) 2 (c) -2 (d) -1

If a,b are the roots of the equation x^(2)+x+1=0, thn a^(2)+b^(2)= a.1b.2c-1d.3

x=2/3 and x = − 3 are the roots of the equation ax^2 + 7 x + b = 0 , find the values of a a n d b .

The roots of the equation |[1,1,1],[a,x,a],[b,b,x]|=0 are (a) 1,1, (b) 1,a (c) 1,b, (d) a,b

If c and d are roots of the equation (x-a) (x-b) - k = 0, then a, b are roots of the equation

If 2 is a root of the equation x^2+b x+12=0 and the equation x^2+b x+q=0 has equal roots, then q= (a) 8 (b) -8 (c) 16 (d) -16
