Answer:

`\left(x-1\right)\left(x-9\right)`

Explanation:

Given: Factor completely
`x^2-10x+9`

Solve:

Break the expression to :
`\left(x^2-x\right)+\left(-9x+9\right)`

Factor out x from x ² -x which is ; x ( x - 1)

Factor out -9 from -9x + 9 which is ; - 9 ( x -1 )

As a result:
`=x\left(x-1\right)-9\left(x-1\right)`

Factor out x - 1

`=\left(x-1\right)\left(x-9\right)`

Finally result:

`=\left(x-1\right)\left(x-9\right)`
