You can put this solution on YOUR website!
$\"4x%5E2-20x%2B25\"$
\n" ); document.write( "This is always a bit more difficult when the coefficient of x^2 is not a 1, but you can still do it!
\n" ); document.write( "The way to think about what the factors are is: What are the factors of 25, which, when added together and then are multiplied by the factors of 4, will give you -20? Ouch, that is a brain cramp. However, I know 5x5=25, and 2x2 is 4, so we can try that to see it it works...
\n" ); document.write( " $\"%282x-5%29%282x-5%29\"$
\n" ); document.write( "Yes, it does. Prove it to yourself by multiplying out these factors and be sure you get the original expression.
