Let's factor a2−8a+16

a2−8a+16

The middle number is -8 and the last number is 16.

Factoring means we want something like

(a+_)(a+_)

Which numbers go in the blanks?

We need two numbers that...

Try -4 and -4:

-4+-4 = -8

-4*-4 = 16

Fill in the blanks in

(a+_)(a+_)

with -4 and -4 to get...

(a-4)(a-4)

(a−4)(a−4)

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!
