Question

is their anyone that can help me with four problems I can not figure them out please???
it says Factor each problem completely. and the first problem is 5x^2y^4z^2 – 15x^3y^5z^3 + 20x^2y^5z

Answer 1

5x^2y^4z^2 – 15x^3y^5z^3 + 20x^2y^5z

Answer 2

that is the first one

Answer 3

7x^3 – 63xy^2 <____ theirs the 2nd one

Answer 4

for the first one
5x²y⁴z² – 15x³y⁵z³ + 20x²y⁵z
you have at least 2 x (x²) in each term : factor it out
at least 4 y (y⁴) and at least 1 z.
factor each of them you get
x²y⁴z * ( 5z – 15xyz² + 20y )

Answer 5

for the second one

7x³ – 63xy²
here you have only one x in comon to each term so it is the only one you can factor out
and you can factor out a 7 ; because 7 * 9 = 63
factor 7x out and you get
7x * ( x² - 9y²)
