If (x)/(5) - 9 = 1 , then x = _____

If (2x^2-3x+1)(2x^2+5x+1)=9x^2 ,then equation has

If 5x +1/(3x)=4 , then what is the value of 9x^2+1/(25x^2) ? यदि 5x +1/(3x)=4 है, तो 9x^2+1/(25x^2) का मान क्या होगा ?

If 3x^2-5x+1=0 , then the value of (x^2+ 1/(9x^2)) is : यदि 3x^2-5x+1=0 , तो (x^2+ 1/(9x^2)) का मान ज्ञात कीजिए ।

If 5f(x)+4f((1)/(x))=x-1,x!=0 then write the value of 9f(2)
