A. Is the following binomial a difference of squares?
\n" ); document.write( "9a^2 – 8b^2
\n" ); document.write( "No; The coefficient of b^2, (8) is not a perfect square
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "B. If one-half a number is subtracted from five-sixths of the number, the difference is 6. Find the number
\n" ); document.write( ":
\n" ); document.write( "Let x = the number, then just write what it says:
\n" ); document.write( ":
\n" ); document.write( "\"If one-half a number is subtracted from five-sixths of the number, the difference is 6.\"
\n" ); document.write( "\"%285%2F6%29x\" - \"%281%2F2%29x\" = 6
\n" ); document.write( ":
\n" ); document.write( "Get rid of the denominator, mult equation by 6
\n" ); document.write( "\"%286%29%285%2F6%29x\" - \"%286%29%281%2F2%29x\" = (6)6
\n" ); document.write( ":
\n" ); document.write( "leave you with:
\n" ); document.write( "5x - 3(1x) = 36
\n" ); document.write( "5x - 3x = 36
\n" ); document.write( "2x = 36
\n" ); document.write( "x = 36/2
\n" ); document.write( "x = 18
