Find the LCM of: \n" ); document.write( "121x^2-9y^2 and 11x^2+3xy \n" ); document.write( ": \n" ); document.write( "Let's factor these and see what we come up with, you can see that the first \n" ); document.write( "expression is the difference of squares, the 2nd we can factor out x, we have: \n" ); document.write( ": \n" ); document.write( "(11x - 3y)(11x + 3y) and x(11x + 3y) \n" ); document.write( ": \n" ); document.write( "therefore factors of the LCM are \n" ); document.write( "x(11x-3y)(11x+3y) \n" ); document.write( ": \n" ); document.write( "FOIL the difference of squares, mult that by x: \n" ); document.write( "x(121x^2 - 9y^2) = 121x^3 - 9xy^2 is the LCM \n" ); document.write( " |
