Answer 1

The answer to the question is b

Answer 2

Answer:

$\largeboxed{7x^2y(x+2xy^2-y)}$

Step-by-step explanation:

$7x^3y+14x^2y^3-7x^2y^2\\\\7x^3y=\boxed7\cdot\boxed{x}\cdot\boxed{x}\cdot{x}\cdot \boxed{y}\\\\14x^2y^3=2\cdot\boxed7\cdot\boxed{x}\cdot\boxed{x}\cdot x\cdot\boxed{y}\cdot y\cdot y\\\\7x^2y^2=\boxed7\cdot\boxed{x}\cdot\boxed{x}\cdot\boxed{y}\cdot y\\\\7x^3y+14x^2y^3-7x^2y^2=\boxed7\cdot\boxed{x}\cdot\boxed{x}\cdot\boxed{y}(x+2\cdot x\cdot y\cdot y-y)\\\\=7x^2y(x+2xy^2-y)$
