Algebra.Com's Answer #17326 by venugopalramana(3286) You can put this solution on YOUR website! Find the constant term that should be added to make the following expression a perfect square trinomial. \n" ); document.write( "x^2 + 3x \n" ); document.write( "TRY COMPLETING THE SQUARE FULLY USING X^2 AND X TERMS \n" ); document.write( "{(X)^2+2*(3/2)*X)}IS UTILISATION OF THE GIVEN TERMS.OK NOW MAKE A PERFECT SQUARE USING FORMULA FOR (A+B)^2=A^2+2AB+B^2 \n" ); document.write( "{(X)^2+2*(3/2)*X)+(3/2)^2}....(3/2)^2=9/4 SHOULD BE ADDED.\r \n" ); document.write( "\n" ); document.write( "answer choice of 9, 9/4, 9/2 or 3/2 \n" ); document.write( "my answer is 9/2 but am not confident it is correct \n" ); document.write( "NO SEE ABOVE ...9/4 IS THE ANSWER. \n" ); document.write( " |
