Question

for what values of a the quadratic equation 30a X square - 6 X + 1 is equal to zero has no real roots​

Answer 1

$30a \times x {}^{2} - 6x + 1 = 0 \\ 30x \times x {}^{2} - 6x = 0 - 1 \\ 24x {}^{2} = - 1 \\ x {}^{2} = - 1 \div 24 \\ x = \sqrt{ - 1 \div 24}$

x=-1/4.89

since ,

if there is any two different variables we can change into one

like in this problem I'm change the a as x because there is two different variables only

I hope you will understand my answer
