(x2-y2+6x+9):(x+y+3)
= [(x+3)2-y2]:(x+y+3)
=(x+3+y)(x+3-y):(x+y+3)
=x+3-y
(x2-y2+6x+9):(x+y+3)
= [(x+3)2-y2]:(x+y+3)
=(x+3+y)(x+3-y):(x+y+3)
=x+3-y
thuc hien phep chia da thuc x^3+x^2-2x cho da thuc x+2
Làm tính chia: (x2 – y2 + 6x + 9) : (x + y + 3)
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
thuc hien phep tinh nhan don thuc vs da thuc
3xn(6xn-3+1)-2xn(9xn-3-1)
thuc hien phep tinh:3*x^2*(6*x^(n-3)+1)-2*x^n*(9*x^(n-3)-1)
Thuc hien cac phep tinh.
a,0,5xy(8y-8x)-6y(y-x)-4xy^2+6xy
khong thuc hien phep tinh hay cm rang A chia het cho B biet rang
A=(x+1)(x+3)(x+5)(x+7)+15 va B = x+6
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 nhan rut gon roi tinh gia tri bieu thuc
B)x(x^2-y)-x^2(x+y)+y(x^2-x) tai x=1/2 va y=-100
