Answer:

The middle number is 14 and the last number is 49.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 14

Multiply together to get 49

Can you think of the two numbers?

Try 7 and 7:

7+7 = 14

7*7 = 49

Fill in the blanks in

(x+_)(x+_)

with 7 and 7 to get...

(x+7)(x+7)

Answer:

(x+7)(x+7)

Answer:

(x + 7) (x + 7)

Explanation:

What's the square root of x^2?

That's x

What's the square root of 49

That's 7

And what makes 14?

7 + 7 = 14

So therefore the answer is (x + 7) (x + 7)
