1. Simplify: 4[a – b(2 + 3a)] – 3a[2+b(4 – a)]
\n" ); document.write( "Work from the inside out. Eliminate parentheses.
\n" ); document.write( "4[a – b(2 + 3a)] – 3a[2+b(4 – a)]
\n" ); document.write( "= 4[a - 2b - 3ab] - 3a[2 + 4b - ab]
\n" ); document.write( "= 4a - 8b - 12ab - 6a - 12b + 3a^2b
\n" ); document.write( "Then combine terms
\n" ); document.write( "= -2a - 20b - 12ab + 3a^2b
\n" ); document.write( "----------------
\n" ); document.write( "2. Simplify: (7x2 – 2y + z) + (3y – z) + (4x2 – 6y)
\n" ); document.write( "Just remove the parentheses and combine terms.
\n" ); document.write( "7x2 – 2y + z + 3y – z + 4x2 – 6y
\n" ); document.write( "= 11x^2 -5y
\n" ); document.write( "
\n" ); document.write( "
\n" );
