RUT GON BIEU THUC:
\(A=3x^{n-2}\left(x^{n+2}-y^{n+2}\right)+y^{n+2}\left(3x^{n-2}-y^{n-2}\right)\)
\(B=x^{10}-7x^9+7x^8-7x^7+...+7x^2-7x+2\)
rut gon (x^2-2)(1-x) + ( x+3)(x^2-3x+9)
Rut gon bieu thuc
3(2^2+1)(2^4+1)(2^8+1)(2^16+1)
rut gon (4x^4-20x^3+13x^2+30x+9)/(4x^2-1)^2
Rut gon bieu thuc sau
3(2*2+1)(2*4+1)(2*8+1)(2*16+1)
1.Rut gon
a. (2+1)*(2^2+1)*(2^4+1)*(2^8+1)
b. 7*(2^3+1)*(2^6+1)*(2^12+1)*(2^24+1)
c. (x^2-x+1)*(x^2+x+1)*(x^2-1)
2. Tìm GTLN của 4x-x^2-1
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 ::)))
rut gon
A=(4x+5)^2-(3x-7)^2-(4x-1)(4x+1)
rut gon (x^2+x+1)(x^2-x+1)(x^4-x^2+1)(x^8-x^4+1) mn giup e vs
