Question

HELP PLEASE ! Factor the polynomial completely.
18x^2y-2y

Answer 1

2y(3x-1)(3x+1) is what I came up with to answer your question, hope this helps!

Answer 2

2y( 3x-1)(3x+1)

Explanation:

18x^2y-2y

Factor out the greatest common factor 2y

2y( 9x^2 -1)

The term in the parentheses is the difference of squares

a^2 - b^2 = (a-b)(a+b)

2y( 3x-1)(3x+1)
