Question

a^3 +(-2a^3) + 3a^3 +(-4a^3)​

Answer 1

Simple:

a³+(-2a³) + 3a³+(-4a³)

Solution

-2 + -a³

= -2a³

Answer 2

Answer:

Answer is -2a^3

Step-by-step explanation:

Question:-

${a}^{3} + ( - 2 {a}^{3} ) + 3 {a}^{3} + ( - 4 {a}^{3} )$

Solution:-

First we have to remove brackets

If negative symbol is multiplied by positive symbol we always get negative symbol

${a}^{3} - 2 {a}^{3} + 3 {a}^{ 3} - 4 {a}^{3}$

Regrouping like terms,

${a}^{3} + 3 {a}^{ 3} - 2 {a}^{3} - 4 {a}^{3}$

If negative symbols are in two numbers we can add,

$\mapsto \: 4 {a}^{3} - 6 {a}^{3}$

$\mapsto \: - 2 {a}^{3}$
