Question

Làm tính chia: (15x3y2- 6x2y – 3x2y2) : 6x2y

Answer 1

(15x³y² - 6x²y - 3x²y²) : 6x²y

\(\dfrac{15x^3y^2}{6x^2y}-\dfrac{6x^2y}{6x^2y}-\dfrac{3x^2y^2}{6x^2y}\)

= \(\dfrac{5}{2}\)xy - \(\dfrac{1}{2}\)y

 Chúc bạn học tốt

Answer 2

Ta có: \(\left(15x^3y^2-6x^2y-3x^2y^2\right):6x^2y\)

\(=\dfrac{15x^3y^2}{6x^2y}-\dfrac{6x^2y}{6x^2y}-\dfrac{3x^2y^2}{6x^2y}\)

\(=\dfrac{5xy}{2}-1-\dfrac{y}{2}\)
