Question

thực hiện phép tính:

a,\(\left(2x^3-x^2+5x\right):x\)

b,\(\left(3x^4-2x^3+x^2\right):\left(-2x\right)\)

c,\(\left(-2x^5+3x^2-4x^3\right):2x^2\)

d,\(\left(x^3-2x^2y+3xy^2\right):\left(\dfrac{-1}{2}x\right)\)

e,\(\left(3\left(x-y\right)^5-2\left(x-y\right)^4+3\left(x-y\right)^2\right):5\left(x-y\right)^2\)

Answer 1

a: \(=2x^2-x+5\)

b: \(=-\dfrac{3}{2}x^3+x^2-\dfrac{1}{2}x\)

c: \(=-x^3+\dfrac{3}{2}-2x\)

d: \(=-2x^2+4xy-6y^2\)

e: \(=\dfrac{3}{5}\left(x-y\right)^3-\dfrac{2}{5}\left(x-y\right)^2+\dfrac{3}{5}\)
