\n" ); document.write( "\n" ); document.write( " 1: What is the problem? What do you need to find or do ? What will your final answer look like?\r
\n" ); document.write( "\n" ); document.write( "we have to find the sum of two rational expressions
\n" ); document.write( "first, we need to factor denominators and , then find common denominator
\n" ); document.write( "final answer will look like one rational expression\r

\n" ); document.write( "\n" ); document.write( "We can add rational expressions in much the same way as we add numerical fractions.
\n" ); document.write( "To add rational expressions with unlike denominators, first find the LCM of the denominator, write each expression using the LCD, add the numerators, and simplify as needed.\r
