To get the GCF we proceed as follow:
9x^2a+9xa^2
factor out 9 we get:
9(x^2a+xa^2)
=factoring out x we get
9x(xa+a^2)
factoring out a we get
9ax(x+a)
therefore the GCF is 9ax
Answer:
Add 64
Step-by-step explanation:
x^2 - 16x
<em><u>If you add 64, you get x^2 - 16x + 64 which factors as (x - 8)^2</u></em>

Answer: Add 64
Answer:
Step-by-step explanation:
a² + b² = c²
3.6² + b² = 7.4²
b² = 7.4² - 3.6² = 41.8
b = √41.8
