Tìm x: 4x+1.(16x2-4x+1)-16x.(x2-5)=17
Tìm x: 4x+1.(16x2-4x+1)-16x.(x2-5)=17
(4x+1)(1-4x+16x^2) - 16x(4x^2-5) = 17 tim x
rút gọn (a^2-1)(a^2-a+1)(a^2+a+1)
tìm x : (4x+1)(16^2-4x+1)-16x(4x^2-5)=17
rút gọn (a^2-1)(a^2-a+1)(a^2+a+1)
tìm x : (4x+1)(16^2-4x+1)-16x(4x^2-5)=17
Giúp tui với!!
38. Chọn câu sai:
A. 16x^2 (x-y) - x + y= (2x-1) (2x+1)(4x^2+1)(x-y)
B. 16x^3 - 54y^5 = 2(2x -3y) (4x^2 + 6xy + 9y^2)
C. 16x^5 - 54y = 2(2x-3y) (2x + 3y)^2
D. 16x^4 (x-y) - x + y = (4x^2 -1 (4x^2 +1) (x-y)
tìm x biết
1/ (3x+1)(3x-1)-(x-2)(x\(^2\)+2x+4)=x(6-x\(^2\))
2/ 27x\(^2\)(x+1)-(3x+1)\(^3\)=-8
3/ (4x+1)(16x\(^2\)-4x+1)-16x(4x\(^2\)-5)=17
tìm x:
b.(2x+1)(16x^4-8x^3+4x^2-2x+1)-(2x-1)(16x^4+8x^3+4x^2+2x+1)=2
