Algebra.Com's Answer #3743 by glabow(165)![]() ![]() ![]() You can put this solution on YOUR website! Simplify 4[6-4(x-y)+6x]-16y \n" ); document.write( "You evaluate exponents and radicals first. There are none. Whew! \n" ); document.write( "Next, evaluate groups. There are two groups. One is contained in the other. That's why the different type of bracketing was used. It need not have been, however. I like to evaluate the contained groups first, so I would do \n" ); document.write( "-4(x-y) first, giving -4x + 4y. \n" ); document.write( "The expression then becomes \n" ); document.write( "4[6-4x+4y+6x]-16y. \n" ); document.write( "The other group, 4[6-4x+4y+6x], gives 24-16x+16y+24x. \n" ); document.write( "The entire expression is now 24-16x+16y+24x-16y. \n" ); document.write( "Addition and subtraction always done last, giving \n" ); document.write( "24 + 8x. \n" ); document.write( "Of course, to complete the simplification you would factor out a common value of 8, giving \n" ); document.write( "8(3+x). \n" ); document.write( " |
