(8x - 15)(8x - 15)

(8x - 25)(8x + 25)

(8x - 15)(8x + 15)

(4x + 15)(4x - 15)

Answer 1

`\displaystyle Unfactourable`

Step-by-step explanation:

This expression is unfactourable with rational numbers. Perhaps you made an errour in your expression. Now, what I think you meant was the expression and factours below:

`\displaystyle 64x^2 - 225 \\ \\ [8x - 15][8x + 15]`

If this was what you meant, then here you are.
