This is the way you complete the square. \n" ); document.write( ": \n" ); document.write( "The rules is divide the coefficient of x by 2, then square that value \n" ); document.write( "That give you the 3rd term in a perfect square: \n" ); document.write( ": \n" ); document.write( "x^2 + 8x + ____ \n" ); document.write( ": \n" ); document.write( "In this problem the coefficient of x is 8 \n" ); document.write( "Divide by 2, results in 4 \n" ); document.write( "Square 4; results is 16 \n" ); document.write( "We have: \n" ); document.write( "x^2 + 8x + 16 \n" ); document.write( "If you factor \n" ); document.write( "(x+4)(x+4); FOIL this and you get the equation above, right? \n" ); document.write( "or \n" ); document.write( "(x+4)^2 \n" ); document.write( " |
