It is always OK to use the quadratic formula. \n" ); document.write( "Indeed, there are many, which will not factor. and that is the only way to do it. \n" ); document.write( "If you can see that it will factor, it saves time and energy to do it that way. \n" ); document.write( "// \n" ); document.write( "//\r \n" ); document.write( "\n" ); document.write( "What is the larger root of \n" ); document.write( " \n" ); document.write( "multiplying by 15 gets rid of the denominators \n" ); document.write( "3x^2 = 5x + 2 \n" ); document.write( ": \n" ); document.write( "3x^2 - 5x - 2 = 0 \n" ); document.write( "Factors \n" ); document.write( "(3x + 1)(x - 2) = 0 \n" ); document.write( "x = 2 is the larger root \n" ); document.write( "; \n" ); document.write( ": \n" ); document.write( "Check solution in the original equation \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
