Question

2 Làm tính chia

a) (4x^6-3x^4+x):(-1/2x) ; b)( 2/3x^2y-7xy+x^3y^2) : (-xy)

c) \(_[\)7(x-y)^4+4(x-y)^3\(]\):(y-x)^2 ; d) 6(x-3y)^4:(5x-15y)

e) (x^3+27y^3):2(x+3y)

Answer 1

a: \(=-8x^5+6x^3-2\)

b: \(=-\dfrac{2}{3}x+7-x^2y\)

c: \(=\dfrac{7\left(x-y\right)^4+4\left(x-y\right)^3}{\left(x-y\right)^2}=7\left(x-y\right)^2+4\left(x-y\right)\)

d: \(=\dfrac{6\left(x-3y\right)^4}{5\left(x-3y\right)}=\dfrac{6}{5}\left(x-3y\right)^3\)
