" If "x^(2)+2ax+a<0AA x in[1,2]" then find set of all possible values of "a

IF both the roots of equation x^(2) -2ax + a^(2) -1=0 lie in the interval (-3,4) , then sum of the integral of a is

Factorise : x^(2)-2ax+(a+b)(a-b)

If x^(2)+2ax+10-3a>0 for all x in R then

Vertex of y=x^(2)-2ax+1 is closest to the origin then

If x+a is a factor of 2x^(2)+2ax+5x+10 , find the value of a.
