Algebra.Com's Answer #32362 by Nate(3500)![]() ![]() ![]() You can put this solution on YOUR website! I take it that the expression you showed is equal to zero: \n" ); document.write( "9x^2 - 12x - 5 = 0 find factors of 9 * -5 = -45 that sum to -12 ~~~> -15,3 \n" ); document.write( "9x^2 - 15x + 3x - 5 = 0 \n" ); document.write( "3x(3x - 5) + 1(3x - 5) = 0 \n" ); document.write( "(3x + 1)(3x - 5) = 0 \n" ); document.write( "3x + 1 = 0 \n" ); document.write( "3x = -1 \n" ); document.write( "x = -1/3 \n" ); document.write( "and \n" ); document.write( "3x - 5 = 0 \n" ); document.write( "3x = 5 \n" ); document.write( "x = 5/3 \n" ); document.write( " |
