Algebra.Com's Answer #363266 by Theo(13342) You can put this solution on YOUR website! x^2 + 5x + 2 is your equation. \n" ); document.write( "that doesn't factor, so use the quadratic formula. \n" ); document.write( "set the equation equal to 0 to get: \n" ); document.write( "x^2 + 5x + 2 = 0 \n" ); document.write( "a = 1 \n" ); document.write( "b = 5 \n" ); document.write( "c = 2 \n" ); document.write( "x = (-b +/- sqrt(b^2-4ac))/(2a) becomes: \n" ); document.write( "x = (-5 +/- sqrt(5^2-4*1*2))/(2*1) which becomes: \n" ); document.write( "x = (-5 +/- sqrt(25-8))/(2*1) which becomes: \n" ); document.write( "x = (-5 +/- sqrt(17))/(2*1) which becomes: \n" ); document.write( "x = (-5 +/- 4.123105626)/2 \n" ); document.write( "x is either equal to -.438447187 or -4.561552813 \n" ); document.write( "you can confirm by substituting these values for x in the equation x^2 + 5x + 2 = 0 to see if those equations hold true.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
