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

A= ( 2×0,5-1 ) ( 5×0.5+3)

A= ( 1 - 1 ) ( 2.5+3 )

A= 0 + 5.5

A = 5.5

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

B = (2×4-1) (5×4+3)

B= (8-1) (20+3)

B = 7 + 23

B = 30

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

C = ( 2×-4 -1 ) ( 5×-4 +3 )

C = ( -8 -1 ) ( -20 + 3 )

C = -9 + -17

C = -26

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

D = ( 2× -0.5 -1) ( 5×-0.5 +3 )

D = (-1-1) ( 2.5+3)

D = -2 + 5.5

D = 3.5

E = 1/3 = 0.33

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

E = ( 2×0.33-1)(5×0.33+3)

E ~ (0.66-1) ( 1.65+3)

E ~ -0.34 + 4.65

E ~ 4.31

F = -3/5 = -0.6

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

F = (2×-0.6-1)(5×0.6+3)

F = (-1.2-1) (3+3)

F = -2.2+ 6

F = 3.8
