Expand then simplify by collecting like terms\r
\n" ); document.write( "\n" ); document.write( "First times the first number together in each of the brackets.
\n" ); document.write( "(in this case times 2a by 5a)= 10a^\r
\n" ); document.write( "\n" ); document.write( "Secondly times the first number in the first bracket by the last number in the seocnd bracket.
\n" ); document.write( "(times 2a by 400 = 8a\r
\n" ); document.write( "\n" ); document.write( "Third times the second number in the first bracket by the first in the second bracket.
\n" ); document.write( "(times -3 by 5a)= -15a\r
\n" ); document.write( "\n" ); document.write( "lastly times the last two numbers of each bracket together.
\n" ); document.write( "(times -3 by 4)= -12\r
\n" ); document.write( "\n" ); document.write( "Then collect the like terms of expanded expression 10a^ +8a-15a-12\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "=10a^-7a-12
\n" ); document.write( "
\n" );
