Algebra.Com's Answer #87016 by tutor_paul(519)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "First, get all the x terms on one side of the equation: \n" ); document.write( " \n" ); document.write( "Divide the coefficient of x by 2 and square the result. Add this result to both sides of the equation: \n" ); document.write( " \n" ); document.write( "Simplify right side of the equation: \n" ); document.write( " \n" ); document.write( "Express the right side as a perfect square: \n" ); document.write( " \n" ); document.write( "Remember the goal is to solve for x. Take the square root of both sides of the equation: \n" ); document.write( "(x+4)=+-sqrt(3) \n" ); document.write( "Since this is a second order equation, x can assume 2 values. Take the case of the \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Now, take the case of \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Plug each of these results into the original equation to check and see if they are right. \n" ); document.write( "================== \n" ); document.write( "good Luck, \n" ); document.write( "tutor_paul@yahoo.com\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
