Let's factor m2 + 16m + 64

The middle number is 16 and the last number is 64.

Factoring means we want something like

(m+_)(m+_)

We need two numbers that...

Add together to get 16

Multiply together to get 64

Can you think of the two numbers?

Try 8 and 8:

8+8 = 16

8*8 = 64

Fill in the blanks in

(m+_)(m+_)

with 8 and 8 to get...

(m+8)(m+8)

Answer:

(m+8)(m+8)
