Algebra.Com's Answer #228683 by nyc_function(2741)![]() ![]() You can put this solution on YOUR website! sqrt{5x + 29} = x + 3\r \n" ); document.write( "\n" ); document.write( "Square both sides to begin. By squaring both sides, you will then be able to remove the radical from the left side.\r \n" ); document.write( "\n" ); document.write( "[sqrt{5x + 29}]^2 = (x + 3)^2\r \n" ); document.write( "\n" ); document.write( "5x + 29 = x^2 + 6x + 9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "0 = x^2 + 6x - 5x + 9 - 29\r \n" ); document.write( "\n" ); document.write( "0 = x^2 + x - 20\r \n" ); document.write( "\n" ); document.write( "0 = (x - 4)(x + 5)\r \n" ); document.write( "\n" ); document.write( "Set each factor to zero and solve for x.\r \n" ); document.write( "\n" ); document.write( "x - 4 = 0\r \n" ); document.write( "\n" ); document.write( "x = 4\r \n" ); document.write( "\n" ); document.write( "OR\r \n" ); document.write( "\n" ); document.write( "x + 5 = 0\r \n" ); document.write( "\n" ); document.write( "x = -5\r \n" ); document.write( "\n" ); document.write( "To make sure that x = 4 and x = -5 are correct, plug those two values for x into the original radical equation given. The correct x value will produce the same answer on both sides of the equation after simplifying. I'll let you do that, however.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
