Question

PLEASE TELL THE CORRECT ANSWER...✅​

Answer 1

Solutions:-

1)

Given that

A = 4x³+6xy

And A+X = 0

=> X = 0+(-A)

=> X = -A

=> X = -(4x³+6xy)

=> X = -4x³-6xy

The expression of X = -4x³-6xy

2)

[(5/x³)+7xy-6y³] + 0 = [(5/x³)+7xy-6y³]

0 is the additive identity element.

3)

Given that

(abc + a³+b³+c³ )+----- = 3abc+2b³

Let (abc + a³+b³+c³ )+ X = 3abc+2b³

=> X = (3abc+2b³)-(abc + a³+b³+c³ )

=> X = 3abc+2b³-abc-a³-b³-c³

=> X = (3abc-abc)+(2b³-b³)-a³-c³

=> X = 2abc+b³-a³-c³

=> X = 2abc-a³+b³-c³

Therefore,

(abc + a³+b³+c³ )+(2abc-a³+b³-c³) = 3abc+2b³

Answer 2

Step-by-step explanation:

And A+X = 0

=> X = 0+(-A)

=> X = -A

=> X = -(4x³+6xy)

The expression of X = -4x³-6xy

2)

[(5/x³)+7xy-6y³] + 0 = [(5/x³)+7xy-6y³]

0 is the additive identity element.

3)

Given that

(abc + a³+b³+c³ )+----- = 3abc+2b³

Let (abc + a³+b³+c³ )+ X = 3abc+2b³

=> X = (3abc+2b³)-(abc + a³+b³+c³ )

=> X = 3abc+2b³-abc-a³-b³-c³

=> X = (3abc-abc)+(2b³-b³)-a³-c³

=> X = 2abc+b³-a³-c³

=> X = 2abc-a³+b³-c³

Therefore,

(abc + a³+b³+c³ )+(2abc-a³+b³-c³) = 3abc+2b³
