Algebra.Com's Answer #154930 by profemmanuel2q@yahoo.com(15) ![]() You can put this solution on YOUR website! find the LCD of: \n" ); document.write( "7/a^2+2a-63 , 8/a+9 \n" ); document.write( "Before you can solve this you need to factorise,a^2+2a-63 \n" ); document.write( "when you factorise a^2+2a-63, you will get (a - 7)(a + 9) \n" ); document.write( "So therefore taking both denominators thats (a + 9) and a^2+2a-63, the LCM is \n" ); document.write( "(a - 7)(a + 9) \n" ); document.write( " |
