Question

5x²-7x+2        Phân tích đa thức thành nhân tử giùm em với

Answer 1

      \(5x^2-7x+2\)

\(=5x^2-5x-2x+2\)

\(=5x\left(x-1\right)-2\left(x-1\right)\)

\(=\left(x-1\right)\left(5x-2\right)\)

Answer 2

\(5x^2-7x+2\)

\(=5x^2-5x-2x+2\)

\(=5x\left(x-1\right)-2\left(x-1\right)\)

\(=\left(5x-2\right)\left(x-1\right)\)

Answer 3

5x^2-7x + 2

= 5x^2 - 5x - 2x + 2 

= 5x( x - 1 ) - 2(x - 1)

= ( x - 1 ) (5x - 2)

Answer 4

\(5x^2-7x+2\)

\(=5x^2-5x-2x+2\)

\(=5x\left(x-1\right)-2\left(x-1\right)\)

\(=\left(5x-2\right)\left(x-1\right)\)

Answer 5

5x²−7x+2

=5x²−5x−2x+2

=5x(x−1)−2(x−1)

=(5x−2)(x−1)
