Answer:

4.
(x + y)(x + 5y)

5.
\left(2m+3\right)\left(m-4\right)

Explanation:

4.

First break it into groups:


\left(x^2+xy\right)+\left(5xy+5y^2\right)

Then factor out x from the first parentheses and 5y from the second one:


x(x+y)
+
5y\left(x+y\right)

Next, factor out x + y from the equation. This gives you:


\left(x+y\right)\left(x+5y\right)

5.

Break it into groups like the last one:


\left(2m^2+3m\right)+\left(-8m-12\right)

Then, factor out m from the first parentheses and -4 from the second parentheses:


m\left(2m+3\right)-4\left(2m+3\right)

Lastly, factor out 2m + 3 from the equation:


\left(2m+3\right)\left(m-4\right)
