\(=\left(x^3+x^2-3x^2-3x+2x+2-4\right):\left(x+1\right)\\ =\left[\left(x+1\right)\left(x^2-3x+2\right)-4\right]:\left(x+1\right)\\ =x^2-3x+2\left(\text{dư }-4\right)\)
1. Chia đa thức:
(x^3y^3 - 1/2xy^3 - x^3y^2) : 1/3x^3y^2
(x^3 + 8y^3) : (x + 2y)
[ 5(a - b)^3 + 2(a - b)^2 ] : (b - a)^2
(x^3 - 3x^2 + x - 3) : (x - 3)
(12x^2 - 14x + 3 - 6x^3 + x^4) : (1 - 4x + x^2)
(2x^2 - 5x^3 + 2x + 2x^4 - 1) : (x^2 - x - 1)
giúp mình nha các bạn! ^^
a) ( 2x^4-5x^2+x^3-3-3x):(x^2-3)
b)(2x^3+5x^2+3):(2x^2-x+1)
c) (2x+4y)^2 : (x+2y)-(9x^3-12x^2-3x):(-3x)-3(x^2+3)
(x^2+1/2x):1/2-(2x+1)^3:(2x+1)^2+(x+1)^5:(x+1)^2=0
1, làm tính chia
a, (2x^3 5x^2+3-2x): ( 2X^2-x+1)
b, (2x^4 -5x^2 + x^3 -3 -3x) : (x^2 -3)
tìm x,biết:
a)(8x^2-4x):(-4x)-(x+2)=8
b)(2x^4-3x^3+x^2):(-1/2x^2)+4(x-1)^2=0
tìm x: \(x^3\left(2x-1\right)^{m+2}:x^3\left(2x-1\right)^{m-1}-3^5:3^2\)
1. Tính: (1/64y3-x):(1/4y-x)
2. Tìm x: (x3-27):(x2+3x+9)+(2x+1)3:(2x+1) = 20
Tìm x, biết:
\(\left(x^2+\dfrac{1}{2}x\right):\dfrac{1}{2}x-\left(2x+1\right)^3:\left(2x+1\right)^2+\left(x+1\right)^5:\left(x+1\right)^2=0\)
tìm x, biết :
a, 5x (x-1) -(1 -x) =0
b, (x - 3)2 - (x +3)2 = 24
c, 2x ( x2 -4) = 0
d, 2(x+5) - x2 - 5x = 0
e, (2x-3)2 - (x +5)2 = 0
f, 3x3 -48x =0
