a = - 1 ;
b = - 2 y
c = 2
POLINOMIOS :
A . 3 - (2 x a) + (5 x b) - c
3 - (2 x -1) + (5 x -2) - 2
3 - (-2) + (-10) - 2
3 + 2 - 10 - 2 = -7, respuesta
B . (a x 4) - (10 ÷ b) - (8 ÷ c)
(-1 x 4) - (10 ÷ -2) - (8 ÷ 2)
(-4) - (-5) - (4)
- 4+ 5 - 4 = -3, respuesta
C . 13 - 3 x [ ( a - b ) x ( b- c ) ]
13 - 3 x [ ( -1 - (-2) ) x ( -2- 2 ) ]
13 - 3 x [ (1) (-4) ]
13 - 3 x [-4]
13 - (-12)
13 + 12 = 25, respuesta
D . ( (-2 x a) + b ) - ( (c x b) - (3 x a) )
( (-2 x -1) + (-2) ) - ( (2 x (-2)) - (3 x (-1)) )
( 2 -2) - (-4) - (-3)
0 + 4 + 3 = 7, respuesta
E . 11 - { a + [ ( 2- (3 X b) ) - ( c + (4 x 2) ) ] }
11 - {-1 + [ ( 2- (3 X (-2)) ) - (2 + (4 x 2) ) ] }
11 - {-1 + [ ( 2- (-6) ) - (2 + (8)) ] }
11 - {-1 + [ ( 2+6) - (2 + (8) ] }
11 - {-1 + [ ( 8) - (10) ] }
11 - {-1 + [-2] }
11 - {-1 -2}
11 - {-3}
11 + 3 = 14, respuesta
