\n" ); document.write( "Let the number be x.

\n" ); document.write( "One-half the number squared is (1/2)x^2.

\n" ); document.write( "16 more than twice the number is 2x+16.

\n" ); document.write( "Write and solve the equation that says those two expressions are equal:

\n" ); document.write( "\"%281%2F2%29x%5E2+=+2x%2B16\"

\n" ); document.write( "It's a quadratic equation. Get everything on one side of the equation (with 0 on the other side) and try to solve using factoring; if it doesn't factor (or you can't see how it factors), use the quadratic formula.

\n" ); document.write( "(If you know the basics about solving quadratic equations, you will start by multiplying the whole equation by 2 to get rid of the fractions....)
