just 2 questions.
Please answer it :)
1)the decimal expansion of 6/1250 will be terminating after how many places of decimals? (how to find this ?)
2)find the value of p so that the quadratic equation p x(x-3) + 9 = 0 is has two equal roots
the denominator is 1250 =
thus the highest power of the prime factors is 4. therefore it will terminate after 4 decimals.
2.
the given equation is
if the equation has equal roots, discriminant = 0
therefore
p can not be zero, for p = 0 , the equations becomes linear equation.
thus p = 4.
hope this helps you.
cheers!!
