Answer 2

Heya...
Here is your answer --

(9x-7)(2x-5) - (3x-8)(5x-3)
Let {(9x-7)(2x-5)} be Part A and {(3x-8)(5x-3)} be Part B

Solving Part A :
=> (9x-7)(2x-5)
=> 9x (2x-5) -7 (2x-5)
=> 18x^2 -45x +35

Solving Part B :
=> (3x-8)(5x-3)
=> 3x (5x-3) -8 (5x-3)
=> 15x^2 -40x +24

PART A - PART B
=> (18x^2 -45x +35) - (15x^2 -40x +24)
=> 18x^2 -45x +35 -15x^2 +40x -24
=> (18x^2 - 15x^2) + (-45x+40x) + (35-24)
=> 3x^2 - 5x + 11

HOPE IT HELPS...!
