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

For all ' x^(prime),x^2+2a x+(10-3a)>0, then the interval in which ' a ' lies is (2004, 1M) a 5 (d) 2

For all 'x', x^2+2ax+(10-3a)gt0 , then the interval .In which 'a' lies is

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 (a)a 5(d)2

for all x in R if mx^2-9mx+5m+1gt0 then m lies in the interval

for all x in R if mx^2-9mx+5m+1gt0 then m lies in the interval

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.

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.
