\n" );
document.write( "3x^2-13x+4=0. I know I have to divide each term by 3 which would give me:\r
\n" );
document.write( "\n" );
document.write( "x^2-13/3x+4/3=0. Then I subtract 4/3 on both sides to get x^2-13/3x=-4/3. I multiply -13/3xand 1/2 to get -13/6x then I square it to get 169/36 which I add to both sides of the equation.
\n" );
document.write( "x^2-13/3x+169/36=-4/3+169/36. Here is where I'm having a hard time and are looking for your help. \n" );

Algebra.Com's Answer #614313 by Timnewman(323)![]() ![]() You can put this solution on YOUR website! 3x²-13x+4=0 \n" ); document.write( "x²-13x/3+4/3=0 \n" ); document.write( "x²-13x/3=-4/3 \n" ); document.write( "take the half of 13/3,square it,then add it to bothside \n" ); document.write( "From the above,half of 13/3 is 26/3 then it's square is 676/9,Then add 676/9 in bothside of the equation, \n" ); document.write( "x²-13x/3+676/9=676/9-4/3 \n" ); document.write( "(x-26/3)²=(676-12)/9 \n" ); document.write( "(x-26/3)²=664/9 \n" ); document.write( "solve it from here!!! \n" ); document.write( " |
