Answer:
1.(x-6)(x-6)
2.(x+9)(x+9)
Step-by-step explanation: solution
1.Let's factor x2−12x+36
x2−12x+36
The middle number is -12 and the last number is 36.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -12
Multiply together to get 36
Can you think of the two numbers?
Try -6 and -6:
-6+-6 = -12
-6*-6 = 36
Fill in the blanks in
(x+_)(x+_)
with -6 and -6 to get...
(x-6)(x-6)
Answer:
(x−6)(x−6)
2.Let's factor x2+18x+81
x2+18x+81
The middle number is 18 and the last number is 81.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 18
Multiply together to get 81
Can you think of the two numbers?
Try 9 and 9:
9+9 = 18
9*9 = 81
Fill in the blanks in
(x+_)(x+_)
with 9 and 9 to get...
(x+9)(x+9)
Answer:
Let's factor x2+18x+81
x2+18x+81
The middle number is 18 and the last number is 81.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 18
Multiply together to get 81
Can you think of the two numbers?
Try 9 and 9:
9+9 = 18
9*9 = 81
Fill in the blanks in
(x+_)(x+_)
with 9 and 9 to get...
(x+9)(x+9)
Answer:
(x+9)(x+9)
