Question

Factor. m2 + 16m + 64

Answer 1

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)

Answer 2

m^2 + 16m +64 = (m+8)^2

Factor using the perfect square rule.
