If f(x) = x2 − 1, and f(2a) = 35, then what could be the value of a ?

When    f(x)=x^2-1
and       f(2a)=35    it means that:    x=2a
                                                     {   x^2-1=35

so: (2a)^2-1=35
      4(a^2)-1=35
      4(a^2)=35+1
      4(a^2)=36    /4
       a^2=9      
       a=3
