Answer:
Explanation:
Let's factor x2+7x+10
x2+7x+10
The middle number is 7 and the last number is 10.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
- Add together to get 7
- Multiply together to get 10
Can you think of the two numbers?
Try 2 and 5:
2+5 = 7
2*5 = 10
Fill in the blanks in
(x+_)(x+_)
with 2 and 5 to get...
(x+2)(x+5)
