(3 x - 2) (4 x+1)- (3 x -2) 4 x +1 , when x = 4
= (10)(17) - (10)(16) - 1
= 170 - 160 - 1
= 9
if you meant:
(3 x - 2) (4 x+1)- (3 x -2)( 4 x +1)
then you get 0 , since (10)(17) - 10(17) = 0
= (10)(17) - (10)(16) - 1
= 170 - 160 - 1
= 9
if you meant:
(3 x - 2) (4 x+1)- (3 x -2)( 4 x +1)
then you get 0 , since (10)(17) - 10(17) = 0
