Question

Chỉ giúp tôi phân tích đa thức ra nhân tử 5(x-3)-x(3-x)

Answer 1

\(5\left(x-3\right)-x\left(3-x\right)=5\left(x-3\right)+x\left(x-3\right)=\left(x-3\right)\left(x+5\right)\)

Answer 2

$=(x+5)(x-3)$

Answer 3

\(5\left(x-3\right)+x\left(x-3\right)=\left(5+x\right)\left(x-3\right)\)

Answer 4

5.(x - 3) - x.(3 - x) = 5.(x - 3) + x.(x - 3) = (5 + x).(x - 3)

Answer 5

(x+5)(x-3)

Answer 6

= \(\left(x+5\right)\left(x-3\right)\)
