thuc hien phep tinh :

a, (x+1)(1+x-x^2+x^3-x^4)-(x-1)(1+x+x^2+x^3+x^4)

b, (2b^2-2-5b+6b^3)(3+3b^2-b)

thuc hien phep tinh : 

a, (x+1)(1+x-x\(^2\)+x\(^3\)-x\(^4\))-(x-1)(1+x+x\(^2\)+x\(^3\)+x\(^4\))

b, (2b\(^2\)-2-5b+6b\(^3\))(3+3b\(^2\)-b)

thuc hien phep tinh:

(x+2)(1+x-x^2+x^3-x^4)-(1-x)(1+x+x^2+x^3+x^4)

thuc hien phep tinh:

(x+2)(1+x-x^2+x^3-x^4)-(1-x)(1+x+x^2+x^3+x^4)

thuc hien phep tinh:

(x+2)(1+x-x^2+x^3-x^4)-(1-x)(1+x+x^2+x^3+x^4)

tính :
a, (x+1).(1+x-x^2+x^3-x^4)-(x-1).(1+x+x^2+x^3+x^4)
b, (2 b^2-2-5b+6b^3) . (3+3b^2-b)

Giup mk not bai nay , dang gap !

Thuc hien phep tinh:

a, (x -2) ^3 -x(x+1)(x-1) + 6x(x -3)

b, (x-2)(x^2 - 2x +4)(x+2)(x^2 +2x + 4)

Thanks moi ng nha !

thuc hien phep chia

a,(7(x^2-1)^4+2(1-x)^3-3(x-1)^2): 2(x-1)^2

b,5(x^3-y^3)+(x-y)^3:(x-y)^2

1, thực hiện phép tính
a, (x+1).(1+x-x^2+x^3-x^4)-(x-1).(1+x+x^2+x^3+x^4)

b, (2 b^2-2-5b+6b^3) . (3+3b^2-b)
