Complete step-by-step answer:

The given expansion is (5−y)2

The expansion is in the form (a−b)2

We apply the formula (a−b)2=a2+b2+2ab

a=5,b=y

So, (5−y)2=(5)2+(y)2−2∗5∗y

⇒ (5−y)2=25+y2−10y

So, we have (5−y)2=25+y2−10y

In 25+y2−10y, coefficient of y is −10

So, the coefficient of (5−y)2 is −10.
