Answer: ( x − 4 ) ( x + 36 )
Step-by-step explanation:
Use the sum-product pattern
^2 + 3
2
− 1
4
4
^2 + 36
− 4
− 1
4
4
Common factor from the two pairs
^2 + 3
6
− 4
− 1
4
4
( + 3
6 ) − 4 ( + 3
6 )
x ( x + 36 ) - 4 ( x + 36 )
Rewrite in factored form
( + 3
6 ) − 4 ( + 3
6 )
( x - 4 ) ( x + 36 )
Solution
( − 4 ) ( + 3
6 )
