Answer:

= - 2 x^{3} + 4x -8

Step-by-step explanation:

The first step is to open the parenthesis,

Since there is a negative sign before the second parenthesis, so the sign of all the values in second parenthesis will be changed and the equation will look something like this

= 2x^{3} + 4x -2 - 4 x^{3}  + 6

The second step is to re arrange the equation

= 2x^{3} - 4 x^{3} + 4x - 2 + 6

The last and final step is to solve the equation

= - 2 x^{3} + 4x -8

This is our answer

Answer:

The difference is -2x³ + 4x + 4.

Step-by-step explanation:

Subtract the two expression as follows:

(2x^{3}+4x-2)-(4x^{3}-6)=2x^{3}+4x-2-4x^{3}+6\\

Combine the like terms together:

                                         =2x^{3}-4x^{3}+4x-2+6

Simplify as follows:

                                         =-2x^{3}+4x+4

Thus, the difference is -2x³ + 4x + 4.

Kendra used these steps to solve the equation 2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?
11Alexandr11 [23.1K]
Hello!

We can solve this algebraically

2x + 5 = 3 + 2(x+1)

Distribute the 2

2x + 5 = 3 + 2x + 2

combine like terms

2x + 5 = 2x + 5

Since both sides of the equation is the same all values of x make the equation true

The answer is A

Hope this helps!
