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)
