Find and correct the errors in the following mathematical statement.

$space space fraction numerator 3 straight x squared plus 1 over denominator 3 straight x squared end fraction space equals space 1 space plus space 1 space equals space 2$

fraction numerator 3 straight x squared plus 1 over denominator 3 straight x squared end fraction space equals space fraction numerator 3 straight x squared over denominator 3 straight x squared end fraction space plus space fraction numerator 1 over denominator 3 straight x squared end fraction

Since

fraction numerator 3 straight x squared space plus space 1 space over denominator 3 straight x squared end fraction space equals space fraction numerator 3 straight x squared over denominator 3 straight x squared end fraction space plus space fraction numerator 1 over denominator 3 straight x squared end fraction

equals 1 space plus space fraction numerator 1 over denominator 3 straight x squared end fraction

∴ The correct statement is

$fraction numerator 3 straight x squared plus 1 over denominator 3 straight x squared end fraction space equals space 1 space plus space fraction numerator 1 over denominator 3 straight x squared end fraction$
