Alex_Mattucci one year ago I need help dividing a polynomial!!! (10x4y3 + 5x3y2 - 15x2y - 25x2y4)/-5x2y

1. Nnesha

Divide the coefficients and for variables apply the exponent rule when we divide same base , subtract their exponents $\huge\rm \frac{ x^m }{ x^n }=x^{m-n}$

2. Nnesha

like for first one $\huge\rm \frac{ 10 x^4y^3}{ -5x^2y^1} =\frac{10}{-5}x^{4-2}y^{3-1}$ y is same as y to the one power

3. Nnesha

subtract exponents and divide the coefficient

4. Alex_Mattucci

Ok,thank you!!!

5. Alex_Mattucci

Just to be correct on this, That would make the answer -2x^2y^2-1xy+3+5y^2 correct @Nnesha?

6. Nnesha

$\huge\rm \frac{ - 25x^2y^4 }{ -5x^2y } = ??$

7. Nnesha

remember y is same as y to the one power (y^1)
