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 :

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 nhan:

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

thuc hien phep tinh:1/(x-1)-(x^3-x)/(x^2+1).(1/(x^2-2x+1)+1/(1-x^2))

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 tinh:3*x^2*(6*x^(n-3)+1)-2*x^n*(9*x^(n-3)-1)

tim x biet,

5^x  + 5^x+2= 650

Thuc hien phep tinh

(1+2+3+4+...+90).(12.34 - 6.68) : (1/3+1/4+1/5+1/6)
