You can put this solution on YOUR website!
-5%28x-3y%29%5E2+%2B+7%283y-x%29=-5%28x-3y%29%5E2+-7%28x-3y%29
That makes you see a %28x-3y%29 common factor, so
-5%28x-3y%29%5E2+%2B+7%283y-x%29=%28x-3y%29%28-5%28x-3y%29-7%29
-5%28x-3y%29%5E2+%2B+7%283y-x%29=highlight%28%28x-3y%29%28-5x%2B15y-7%29%29
There are other equivalent alternative factored forms,
because you can play with the order of terms and the minus signs,
as in the examples below.
-5%28x-3y%29%5E2+%2B+7%283y-x%29=highlight%28%28x-3y%29%283y-15x-7%29%29
-5%28x-3y%29%5E2+%2B+7%283y-x%29=highlight%28-%28x-3y%29%2815x-3y%2B7%29%29
-5%28x-3y%29%5E2+%2B+7%283y-x%29=highlight%28%283y-x%29%2815x-3y%2B7%29%29
