E=(3x-1)(2x+5)+7(3x-1)
=(3x-1)(2x+5+7)
=(3x-1)(2x+12)

F=(x-4)(7-x)+(x+3)(7-x)
=(7-x)(x-4+x+3)
=(7-x)(2x-1)

E = (3x-1)(2x+5)+7(3x-1)
   = (3x-1)(2x+5+7)
   =(3x-1)(2x+12)
F = (x-4)(7-x)+(x+3)(7-x)
   = (7-x)(x-4+x+3)
   =(7-x)(2x-1)
E = (3 x-1)(2x+5)+7(3 x-1)
E = (3 x-1)(2x +5+7)
E =(3 x-1)(2x+12)
F = (x-4)(7-x)+(x+3)(7-x)
F = (7-x)(x-4+x+3)
F =(7-x)(2x-1)
