Answer:
2(9x-32)
Step-by-step explanation:
9x(2)-64
18x-64
=2(9x-32)
[tex] {9x}^{2} - 64[/tex]
- We have to factorise it using the identity: x² - y² = (x - y)(x + y)
- We know 3² = 9 and 8² = 64.
[tex] {(3x)}^{2} - (8)^{2} \\ [/tex]
- Now, use the identity I have mentioned.
[tex](3x - 8)(3x + 8)[/tex]
Answer:
(3x - 8)(3x + 8)
