Algebra.Com's Answer #548473 by ewatrrr(24785)![]() ![]() You can put this solution on YOUR website! 9(y-1)^2-25 = 9(y^2 - 2y + 1) - 25 = 9y^2 - 18y -16 \n" ); document.write( "9y^2 - 18y -16 = (3y -8)(3y+2) \n" ); document.write( "F First terms \n" ); document.write( "O Outside terms 6y \n" ); document.write( "I Inside terms -24y \n" ); document.write( "L Last terms \n" ); document.write( " \n" ); document.write( " |
