Two no. Are like that if they are added the product is 56 and when they 2 no. Are added with their squares the sum is 128
\n" ); document.write( ":
\n" ); document.write( "I think you mean \"When two numbers are multiplied the product is 56\" and
\n" ); document.write( "When the squares are added the sum is 128
\n" ); document.write( ":
\n" ); document.write( "Let the two number be a & b
\n" ); document.write( ":
\n" ); document.write( "when multiplied: a*b = 56
\n" ); document.write( "When squares added: a^2 * b^2 = 128
\n" ); document.write( "we can rearrange this to
\n" ); document.write( "b^2 = 128 - a^2
\n" ); document.write( "b = \"sqrt%28128-a%5E2%29\"
\n" ); document.write( "then from the 1st equation
\n" ); document.write( "a*\"sqrt%28128-a%5E2%29\" = 56
\n" ); document.write( "square both sides
\n" ); document.write( "a^2(128-a^2) = 3136
\n" ); document.write( "128a^2 - a^4 = 3176
\n" ); document.write( "0 = a^4 - 128a^2 + 3136
\n" ); document.write( "Using the quadratic formula we get two solutions
\n" ); document.write( "a^2 = 33
\n" ); document.write( "a = \"sqrt%2833%29\"
\n" ); document.write( "a = 5.746
\n" ); document.write( "and
\n" ); document.write( "a^2 = 95
\n" ); document.write( "a = \"sqrt%2895%29\"
\n" ); document.write( "a = 9.746
\n" ); document.write( ":
\n" ); document.write( "a = 5.746, then b = 9.746
\n" ); document.write( "a = 9.746, then b = 5.746
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this in the original problem
\n" ); document.write( "5.746 * 9.746 = 56.00
\n" ); document.write( "and
\n" ); document.write( "5.746^2 + 9.746^2 = 128.00
\n" ); document.write( "
\n" );
