Multiply everything by 4 to clear fractions \n" ); document.write( "8x^2+14x+3=0 \n" ); document.write( "guess and check is (4x+1)(2x+3)=0, and zeros are -1/4 and -3/2 \n" ); document.write( "=========== \n" ); document.write( "also \n" ); document.write( "grouping 8x^2+2x+12x+3=2(4x+1)+3(4x+1) \n" ); document.write( "========== \n" ); document.write( "also convert equation to \n" ); document.write( "x^2+14x+24, dividing first term by 8 and multiplying constant by 8 \n" ); document.write( "factor to (x+12)(x+2) \n" ); document.write( "divide constant by 8 and reduce to lowest terms (x+(3/2))(x+(1/4)) \n" ); document.write( "put the denominator in front (2x+3)(4x+1) \n" ); document.write( " |
