Respuesta:
A: = 3x^2 + 8x^3
B:= -15a^4b^4 + 2a^3b^4
C: = 2a^3 - 1a^4 - 9b^2 + 6d^3 - f
D:= -8
E:= = 8a^2 + 5m^3
F:= -12b
G:= 51x/56 + 170/56
H: = -4a - 5b
paso a paso:
-De 3x^2, restar -8x^3:3x^2 - (-8x^3) = 3x^2 + 8x^3
-Restar -2a^3b^4 de -15a^4b^4:-15a^4b^4 - (-2a^3b^4) = -15a^4b^4 + 2a^3b^4
-De a^3 - 9b^2 + 6d^3 - 2f, restar -a^3 + 1a^4 - f:(a^3 - 9b^2 + 6d^3 - 2f) - (-a^3 + 1a^4 - f) = 2a^3 - 1a^4 - 9b^2 + 6d^3 - f
-De 1/3(y + 2) + 2/3(y - 5), restar -y/6 + 5/6 con y = -3:Con y = -3:1/3(-3 + 2) + 2/3(-3 - 5) = 1/3(-1) + 2/3(-8) = -1/3 - 16/3 = -17/3-(-3)/6 + 5/6 = 1/2 + 5/6 = 7/6-17/3 - 7/6 = -17/3 - 7/6 * 2/2 = -17/3 - 7/3 = -24/3 = -8
-De la suma de 8a^2 + 5, con -2 + 7 m^3, restar la suma de 2m^3 + 3:(8a^2 + 5) + (-2 + 7m^3) = 8a^2 + 3 + 7m^3(2m^3 + 3) = 2m^3 + 38a^2 + 3 + 7m^3 - (2m^3 + 3) = 8a^2 + 5m^3
-Restar la suma de 2a + b con a = 3b, de la suma de -7a + 2b con a = b:Con a = 3b:2a + b = 2(3b) + b = 6b + b = 7b-7a + 2b = -7(b) + 2b = -7b + 2b = -5b-5b - 7b = -12b
-Restar 5/8 x - 6/7 x de la solución de x + 5e con e = 2/3:Con e = 2/3:x + 5e = x + 5(2/3) = x + 10/35/8x - 6/7x = (5/8 - 6/7)x = (35/56 - 30/56)x = 5/56xx + 10/3 - 5/56x = (56x + 170 - 5x)/56 = 51x/56 + 170/56
-De la diferencia entre 5a - 2b y 2a - b, restar la suma de 3a + 4b:(5a - 2b) (2a - b) = 3a - b3a + 4b(3a - b) - (3a + 4b) = -4a - 5b
