\(1,\\ a,=\left(x+2\right)\left(x^2-2x+4\right)\\ b,=\left(x-4\right)\left(x^2+8x+16\right)\\ c,=\left(3x+1\right)\left(9x^2-3x+1\right)\\ d,=\left(4m-3\right)\left(16m^2+12m+9\right)\\ 2,\\ a,=x^3+125\\ b,=1-x^3\\ c,=y^3+27t^3\)
a)
\(=\left(x+2\right)\left(x^2-2x+4\right)\)
b)
\(=\left(x-4\right)\left(x^2+4x+16\right)\)
c)=\(\left(3x+1\right)\left(9x^2-3x+1\right)\)
d)
=\(\left(4m-3\right)\left(16m^2+12m+9\right)\)
2)
a)
\(=x^3+125\)
\(\)b)\(=1-x^3\)
c)
=\(y^3+27t^3\)
Bài 1:
a: \(x^3+8=\left(x+2\right)\left(x^2-2x+4\right)\)
b: \(x^3-64=\left(x-4\right)\left(x^2+4x+16\right)\)
c: \(27x^3+1=\left(3x+1\right)\left(9x^2-3x+1\right)\)
d: \(64m^3-27=\left(4m-3\right)\left(16m^2+12m+9\right)\)
