Question

For what value of A quadratic equation 30axx-6x+1=0 has no real roots

Answer 1

Given the quadratic equation is:

30axx- 6x+10=0

Also it has no real roots

therefore, b2. - 4ac<o

in equation, b=6, a=30a, c= 1

b2 - 4ac=0

6*6-4*30a*1=0

36-120a=0

-120a= -36

120a=36

a=36/120

a=6/20

a=3/10
