factor 2x^2-7x-9

Answer 1

(x + 1 ) (2x-9)

Explanation:

Break The expression into groups

= (
`2x^(2) +2x)+(-9x-9)`

Factor out 2x from
`2x^(2)` + 2x: 2x (x + 1)

and then you want to factor out the -9x - 9 -9( x + 1 )

and that equals 2x( x + 1 )
`-9(x+1)`

And now do it again Factor out common term x + 1

and now it " Equals"
`(x + 1)(2x-9)`
