Create a real-life situation that fits into the equation (x+4)(x-7) = 0 and express the situation as the same equation.
\n" ); document.write( ":
\n" ); document.write( "A simple problems would be. You want a rectangular area of 28 sq/ft
\n" ); document.write( "You want the length to be 3 ft longer than the width, Find the dimensions:
\n" ); document.write( ";
\n" ); document.write( "Let x = length
\n" ); document.write( "then
\n" ); document.write( "(x-3) = width
\n" ); document.write( "and
\n" ); document.write( "Area = x(x-3) = x^2 - 3x
\n" ); document.write( ":
\n" ); document.write( "Area equation:
\n" ); document.write( "x^2 - 3x = 28
\n" ); document.write( ":
\n" ); document.write( "A quadratic equation
\n" ); document.write( "x^2 -3x - 28 = 0
\n" ); document.write( ":
\n" ); document.write( "factor this to:
\n" ); document.write( "(x-7)(x+4) = 0
\n" ); document.write( ":
\n" ); document.write( "Positive solution:
\n" ); document.write( "x = +7 is the length
\n" ); document.write( "
\n" );
