a, = 7x.(2x+y)/(2x+y).(2x-y) = 7x/2x-y
b, = 2.(x^3-4)/2x.(x^2-4) = x^3-4/x.(x^2-4)
k mk nha
bạn kia đúng rùi đó
tk cho mình nha
Rut gon phan thuc: (x^(3)-x^(2)-x-2)/(x^(5)-3x^(4)+4x^(3)-5x^(2)+3x-2)
Minh that su da bo tay vs bai tap nay roi! Cac ban hay giup minh nhe! Minh xin cam on!
phan tich da thuc thanh nhan tu
1) X3+ 6x2 + 12xy + 8
2) x4- 4x3- 8x2 + 8x
3) x4+ 2x3 + x2- y2
giup minh nhe cam on
Rut gon a biet a=(x^2-2x/2^2+8+2x^2/8-4x+2x^2-x^3)x(1-1/-2/^2)
Ai giup minh minh tick nha ::)))
A= 2x^2 +2y^2 -x^2y + z -y^2z - 2
Rut gon bieu thuc
mn giup nhanh nha, thanks trc
phan tich da thuc sau thanh nhan tu
x^3+2x^2+x+2
giup minh nhe cam on nhieu
rut gon phan thuc A=(x^3-6x+7)/(x^3+5x^2-2x-24)
RUT GON PHAN THUC
\(\frac{y^2-x^2}{x^3-3x^2y+3xy^2-y^3}\)
cm bieu thuc sau luon am voi moi xy
A=-x2-y2+8x+4y-21
giup minh nha . cam on
giup mink nhe !!
rut gon bieu thuc sau
(2x-y+5)^2+(4x-2y+10)(y-2x)+(2x-y)^2
