Help to solve this problem? 27x3y2 –18x4y +9x2y / 9x2y?

Answer 1

I have to guess at powers and parans. Which i may get wrong. You need to state your problems unambiguously.

27x³y² –18x⁴y + (9x²y / 9x²y)

9x²y's cancel

27x³y² –18x⁴y

9x²y (3xy - 2x²)

.

Answer 2

So, the first step is to look at the top and try to factor out anything from it. 27x^3y^2 - 18x^4y + 9x^2y. The greatest thing that can be broughout out is a 9x^2y.

This leaves you with (9x^2y)(3xy - 2x^2 + 1). Looking at the original problem, we notice we can cancel out the 9x^2y because it is in the numerator and denominator of the fraction.

Therefore, you get 3xy - 2x^2 + 1.

Answer 3

27x^3y^2-18x^4y+9x^2y/ 9x^2y

9x^2y(3xy-2x^2+1)/9x^2y

3xy-2x^2+1
