Algebra.Com's Answer #207351 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! You need to either divide (x-2) or (x+4) into x^2+2x-8 \n" ); document.write( " or factor x^2+2x-8 \n" ); document.write( "we are looking for factors of -8 which add up +2 \n" ); document.write( "4 -2 fit the bill\r \n" ); document.write( "\n" ); document.write( "(x+4)/(x^2+2x-8)=(x+4)/(x+4)(x-2)=1/(x-2) \n" ); document.write( " |
