Question

Can someone answer this w²+7w-18

Answer 1

(w−2)(w+ 9)

Explanation:

Grouping

Step 1:

Use the sum-product pattern

w² + 7 − 18

w² + 9 − 2 −18

Step 2:

Common factor from the two pairs

w²+ 9 − 2 − 18w

( w+ 9) − 2( w+ 9)

Step 3:

Rewrite in factored form

(w + 9) − 2( w+ 9)

(w−2)(w+9)

Answer 2

Using the "AC Method" I got (w - 2) (w + 9)
