$(10x-y)^{2}$

Step-by-step explanation:

In order to factor the given trinomial, you can rewrite it as follows:

The square root of the first term $100x^{2}$ is:

$\sqrt{100x^{2} } = \sqrt{100}(\sqrt{x^{2} }) = 10x$

The square root of the last term $y^{2}$ is:

$\sqrt{y^{2} } = y$

So you can rewrite it as:

$(10x)^{2} -20xy + (y)^{2}$

The term -20xy can be written as: -2(10xy)

So, notice that the first and last term are perfect squares and the other term is two times the product of the first and last terms. Because of that, you can use the Perfect Square Trinomials form which is:

$(ax)^{2} - 2axb + (b)^{2} = (ax-b)^{2}$

In this case, a=10 and b=y

Then you obtain:

$(10x-y)^{2}$
