Question

How do you factor the polynomials `hj-2h+5j-10`?

Answer 1

`(j-2)(h+5)`

Explanation:

`"group the terms as follows"`

`color(blue)(hj-2h)color(red)(+5j-10)`

`"take out a common factor of h and 5 from the groups"`

`rArrh(j-2)+5(j-2)`

`"the factor " (j-2)" is common to both terms and can be "`
`"taken out as a common factor"`

`rArr(j-2)(h+5)`
