Algebra.Com's Answer #8087 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! 14+3x(x+2)=-7x \n" ); document.write( "14+3x^2+6x+7x=0 \n" ); document.write( "3x^2+13x+14=0 \n" ); document.write( " now find 2 factors for the product of coefficient of x^2 (3) and constant term (14) which will add up to the coefficient of x (13) \n" ); document.write( " the 2 factors of 3*14=42 which add up to 13 are 6 and 7.hence \n" ); document.write( " 3x^2+6x+7x+14=0 \n" ); document.write( " 3x(x+2)+7(x+2)=0..NOTE THAT THIS COULD BE WRITTEN DIRECTLY FROM FIRST TWO STEPS NAMELY 14+3x(x+2)=-7x \n" ); document.write( " 14+3x^2+6x+7x=0 \n" ); document.write( " but i showed you the working to do any other problem. \n" ); document.write( " so (x+2)(3x+7)=0 \n" ); document.write( " x+2=0 OR 3x+7=0 \n" ); document.write( " x=-2 OR 3x=-7..x=-7/3\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
