Question

Please help! factor 2x^2-7x-9

Answer 1

Answer:

(x + 1 ) (2x-9)

Step-by-step 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" $(x + 1)(2x-9)$
