Question

Phân tích đa thức thành nhân tử

9+(x^2+1)-6(x^2+1)

Answer 1

\(9\left(x^2+1\right)-6\left(x^2+1\right)\)

\(=\left(9-6\right)\left(x^2+1\right)\)

\(=3\left(x^2+1\right)\)

Answer 2

\(9+\left(x^2+1\right)-6\left(x^2+1\right)\)

\(=\left(x^2+1\right)\left(1-6\right)+9\)

\(=\left(x^2+1\right)\left(-5\right)+9\)

\(=9-5\left(x^2+1\right)\)
