Question

realizar las siguientes sumas a (5x²+7x+8)+(3x+9)
b (4m²-2mn-5n)+ (6m²+7mn)
c (-9a³b²+7a²b-6)+(12a³b²-9a²b-5)
d (-15xy²+8x²y-9x)+(-18x²y-3x+6)
e (1/2m³-2/3m²)+(-2/5m³+1/6m²)
f (3/4a²b-1/7ab²)+(1/6a²b+3/2ab²)

Answer 1

a) (5x²+7x+8)+(3x+9)
5x^2 + 7x + 3x + 8 + 9
5x^2 + 10x + 17

b) (4m²-2mn-5n)+ (6m²+7mn)
10m^2 + 5mn - 5n
5 (2m^2 + mn - n)

c) (-9a³b²+7a²b-6)+(12a³b²-9a²b-5)
3(a^3)(b^2) - 2(a^2)(b) - 11

d) (-15xy²+8x²y-9x)+(-18x²y-3x+6)
-15(x)(y^2) - 10(x^2)(y) - 12x + 6


e) (1/2m³-2/3m²)+(-2/5m³+1/6m²)
(1/2 - 2/5) m^3 + (-2/3 + 1/6) m^2
( 5 - 4/ 10) m^3 + (-4 + 1/ 6) m^2
1/10 m^3 - 1/2 m^2

f) (3/4a²b-1/7ab²)+(1/6a²b+3/2ab²)
(3/4 + 1/6) a^2 + (-1/7 + 3/2) ab^2
