15(25x {}^{2}  + 16 - 40x) - 10(5x - 4) \\  = 375x {}^{2} + 240 - 600x - 50x + 40 \\  = 375x {}^{2}  - 650x + 280 \\  = 5(75x {}^{2}  - 130x  + 56 ) \\  = 5(75 x {}^{2}  - 60x - 70x + 56) \\  =  5(15x)(5x - 4) - (14)(5x - 4) \\  = 5(15x - 14)(5x - 4)

Bonjour!

=> 15(5x - 4)² - 10(5x - 4)

=> 15(5x - 4)(5x - 4) - 10(5x - 4)

=> (5x - 4)(15(5x - 4) - 10)

=> (5x - 4)(75x - 60 - 10)

=> (5x - 4)(75x - 50)

=> (5x - 4)(25(3x - 2))

=> 25(5x - 4)(3x - 2)

Hope this helps...:)
