Question

x² - 25 + xy +5y

Answer 1

\(x^2-25+xy+5y\)

\(=\left(x^2-25\right)+\left(xy+5y\right)\)

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

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

Answer 2

\(x^2-25+xy+5y\)

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

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

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