Answer:

9( x-3) (x-1)

Explanation:

(5x − 6)^2 − (4x − 3)^2

This is the difference of squares a^2 - b^2 = ( a-b) (a+b)

(5x − 6)^2 − (4x − 3)^2 where a = 5x-6 and b = 4x-3

( 5x-6 - (4x-3)) ( 5x-6 +(4x-3)

Distribute

( 5x-6 -4x+3) ( 5x-6 +4x-3)

Combine like terms

(x-3) ( 9x-9)

Factor out the 9

9( x-3) (x-1)
