tìm x biết:
(x+3)^3-x(3x+1)+(2x+1)(4x^2-2x+1)-3x^2=54
Tìm x, biết:
a) (x-3)(x^2+ 3x +9)+x(2+x)(2x-x)=1
b) (x+3)^3 -x(3x+1)^2+(2x+1)(4x-2x+1)=54
Tìm x biết (x+3)^3-x(3x+1)^2+(2x+1)(4x^2-2x+1)-3x^2=54
Mình đang cần gấp các bạn giúp mình nhé!!
Tìm x: \(\left(x+3\right)^3-x\left(3x+1\right)^2+\left(2x+1\right)\left(4x^2-2x+1\right)-3x^2=54\)
tìm x biết
a) (x+3)2-x(3x+1)2+(2x+1)(4x2-2x+1)-2x2=54
b)(x+3)3-(x-3)(x2+3x+9)+6(x+1)2+3x2=-33
Tìm x biết
a) \(\left(x+3\right)^3-x\left(3x+1\right)^2+\left(2x+1\right)\left(4x^2-2x+1\right)-3x^2=54\)
Tìm x
a,(x+3)3-x(2x+1)2+(2x+1)(4x2-2x+1)-3x2=54
b,(x-3)3-(x-3)(x2+3x+9)+6(x+1)2+3x2=33
tìm x,biết
a) (x+3)3 - x(3x+1)2 + (2x+1)(4x2 - 2x + 1) - 3x2 = 54
b) (x-3)3 - (x-3)(x2+3x+9) + 6(x+1)2 + 3x2 = -33
Tìm x biết
a) x(x-5) (x+5)-(x+2) (x2-2x+4)=3
b) (x+3)3-x(3x+1)2+(2x+1) (4x2-2x+1)-3x2=54
c) (x-3)2-(x-3) (x2+6x+9)+6(x+1)2+3x2=-33
