F= (5x+2)²+(x-4)(5x+2)

F= (5x+2)(5x+2+x-4)

E= (5x+2)(6x-2)

E= 2(5x+2)(3x-1)

G= (4x+7)(4x+7- 5x + 3)

G= (4x+7)(-x+10)

G= - (4x+7)(x-10)

H= 16-9x²

H= - (3x-4)(3x+4)

I= (2x+5)²-(x-7)²

I=  (2x+5-x+7)(2x+5+x-7)

I= (x+12)(3x-2)

J= (10x-5)²-(3x-1)²

J= (10x-5-3x+1)(10x-5+3x-1)

J= (7x-4)(13x-6)
