Cho 2 đa thức P(x)=6x^3-3x^2+5x-1
Q(x)=-6x^3+3x^2-2x+7
1).......
2)tính P(x)-Q(x)
3) (-3x^3+15x^2+81x):(-3x)
thực hiện các phép tính sau:
a,3x^2.(2x^3-x+5)=6x^5-3x^3+15x^2
b,(4xy+3y-5x)x^2y=4x^3y^2+3x^2y^2-5x^3y
Tìm x biết :
a, 4.(18 - 5x) - 12.(3x - 7) = 15.(2x - 16) - 6(x + 14)
b, 5.(3x + 5) - 4.(2x - 3) = 5x + 3.(2x + 12) + 1
c, 2.(5x - 8) - 3.(4x - 5) = 4.(3x - 4) + 11
d, (3x + 2)(2x + 9) - (x + 2)(6x + 1) = (x + 1) - (x - 6)
e, (8x - 3)(3x + 2) - (4x + 7)(x + 4)= (2x + 1)(5x - 1) - 33
: Tìm x, biết:
a) 3x( 4x- 1) - 2x(6x- 3 )30 b) 2x(3-2x) + 2x(2x-1)15
c) (5x-2)(4x-1) + (10x +3)(2x - 1)1 d) (x+2) (x+2)- (x -3)(x+1) 9
e) (4x+1)(6x-3) 7 + (3x – 2)(8x + 9) g) (10x+2)(4x- 1)- (8x -3)(5x+2) 14
