Question

Factor the following expression.
15vx^2y^7-20v^3x^5

Answer 1

5vx^2(3y^7 - 4v^2x^3)

Answer 2

basically you have to take out like expressions. for 15 and 20 a comon multiple is 5 so bring that out. then v is in both parts so bring that out. x^2 is in both parts so you bring that out. y is not in both so you cannot bring that out nor the remaining x^3. because you bring 5vx^2 out of the two equations you then have to divide the two parts by that so that youre left with the remainder and your left with the above answer.
