For all `' x^(prime),x^2+2a x+(10-3a)>0,` then the interval in which `' a '` lies is (a)`a<-5` (b) `-5ltalt2` (c)`agt5` (d) `2ltalt5`

For all 'x', x^(2) + 2ax + 10 - 3a gt 0 , then the interval in which 'a' lies is

For all x,x^(^^)2+2ax+10-3a>0', then the interval in which a lies is

For all 'x', x^(2)+2ax+10-3a gt 0 , Statement 1 : the interval in which 'a' lies is -5 lt a lt 2 because Statement 2 : the sign of coefficient of x^(2) and the quadratic expression are same for all R iff the discriminant is negative.

If (y^(2)-5y+3)(x^(2)+x+1)<2x for all x in R, then fin the interval in which y lies.

If x is real and 5x^(2)+2x+9>3x^(2)+10x+7, then x lies in the interval

If x is real and 2x^(2)-4x+5>0, then x lies in the interval

If log_(3x+5)(ax^(2)+8x+2)>2 then x lies in the interval
