\"x\"= the smallest of the two numbers
\n" ); document.write( "\"x%2B24\"= the other number
\n" ); document.write( "\"x%2Bx%2B24\"= their sum
\n" ); document.write( "\"x%28x%2B24%29\"= their product
\n" ); document.write( "\"y=%28x%2Bx%2B24%29%2B%28x%28x%2B24%29%29\"= the result of adding their sum and their product.
\n" ); document.write( "We need to find the value of \"x\" that minimizes the y value for that function.
\n" ); document.write( "
\n" ); document.write( "Let's simplify that expression:
\n" ); document.write( "\"y=%28x%2Bx%2B24%29%2B%28x%28x%2B24%29%29\"
\n" ); document.write( "\"y=%282x%2B24%29%2B%28x%5E2%2B24x%29\"
\n" ); document.write( "
\n" ); document.write( "\"y=x%5E2%2B26x%2B169-169%2B24\"
\n" ); document.write( "\"y=%28x%2B13%29%5E2-169%2B24\"
\n" ); document.write( "\"y=%28x%2B13%29%5E2-145\"
\n" ); document.write( "As \"%28x%2B13%29%5E2%3E0\" for all \"x%3C%3E-13\" and \"%28x%2B13%29%5E2=0\" for \"x=-13\",
\n" ); document.write( "\"y=%28x%2B13%29%5E2-145%3E-145\" for all \"x%3C%3E-13\" and \"y=%28x-13%29%5E2-145=-145\" is the minimum \"y\" for \"highlight%28x=-13%29\"
\n" ); document.write( "So \"x=highlight%28-13%29\" and \"x%2B24=-13%2B24=highlight%2811%29\" are the two numbers we were looking for.
\n" ); document.write( "
\n" ); document.write( "WITH FORMULAS:
\n" ); document.write( "THe formulas you were given may be slightly different.
\n" ); document.write( "You were probably given \"y=ax%5E2%2Bbx%2Bc\" as general formula for the quadratic function, and
\n" ); document.write( "\"x=-b%2F2a\" as the formula to find the x-coordinate of the minimum.
\n" ); document.write( "In this case, \"a=1\", \"b=26\", and
\n" ); document.write( "\"x=-26%2F%282%2A1%29=-26%2F2=highlight%28-13%29\" is the x-coordinate of the minimum.
\n" ); document.write( "The two numbers are \"x=highlight%28-13%29\" and \"x%2B24=-13%2B24=highlight%2811%29\"
\n" ); document.write( "
\n" );
