Question

X squared + 32x -144

Answer 1

Answer: ( x − 4 ) ( x + 36 )

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 )
