Question

phân tích đa thức thành nhân tử

\(x^3-x^2+16x-16\)

Answer 1

x³ - x² + 16x - 16 = x²(x - 1) + 16(x - 1) = (x² + 16)(x - 1)

Answer 2

x^3-x^2+16x-16 = (x^3-x^2)+(16x-16) = x^2.(x-1) + 16.(x-1) = (x-1)(x^2+16)

Answer 3

\(x^3-x^2+16x-16\)

\(=x^2\left(x-1\right)+16\left(x-1\right)\)

\(=\left(x-1\right)\left(x^2+16\right)\)

Answer 4

\(x^3-x^2+16x-16\)

\(=x^2\left(x-1\right)+16\left(x-1\right)\)

\(=\left(x-1\right)\left(x^2+16\right)\)
