Question

18x^2y^2-9xy^3 what are the steps to factoring then subtracting and simplifying this

Answer 1

could you factor out a 9

Answer 2

_?

Answer 3

it's supposedly a polynomial

Answer 4

does anyone know how to do this?

Answer 5

did you mean 18x^2*y^2 .... or is it as it is?

Answer 6

as it is

Answer 7

how do you factor it

Answer 8

ok so if you've got a power of a power its like multiplying the two in your example the 2 is the power of 2y which is the power of 18x so you just multiply the 2 and 2y and you get 18x^4y - 9xy^3 now if you want to simplify it you can get 9x out of the brackets and you'll get 9x * [ x^(4y-1) - y^3 ] which is not that beautiful.
