Question

phân tích thành nhân tử

x^2-3x+2

Answer 1

(x-2)*(x-1)

Answer 2

(x-2)(x-1)

Answer 3

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

Answer 4

  x^2 - 3x + 2

= x^2 - x - 2x + 2

= (x^2 - x) - (2x - 2)

= x(x - 1) - 2(x - 1)

= (x - 1)(x - 2)
