Simplify (8j^3 - 3j^2 + 5)-(4j^3+8j^2+7j-6)

Answers

Answer:

4j^3 + 5j^2 + 7j - 1

Step-by-step explanation:

(8j^3 - 3j^2 + 5)-(4j^3+8j^2+7j-6)

Distribute the -1 in front of the (4j^3+8j^2+7j-6)

8j^3 - 3j^2 + 5 - 4j^3 + 8j^2 + 7j - 6

We can combine anything with the same exponent number that "j" is raised to

8j^3 - 4j^3 = 4j^3

-3j^2 + 8j^2 = 5j^2

7j is just 7j since there is nothing else with just j in it

5 - 6 = -1

Add these together

4j^3 + 5j^2 + 7j - 1 is our final answer

Take 4a - 3b + 2c from 2a - 3b + 4c.

-2a + 2c
-2a - 2c
2a + 2c
2a - 2c

Answers

Answer:

Option 1 $-2a+2c$

Step-by-step explanation:

To find : Take $4a - 3b + 2c$ from $2a - 3b + 4c$ .

Solution :

The equation $4a - 3b + 2c$ ....(1)

$2a - 3b + 4c$ ....(2)

Taking (1) from (2) means subtracting equitation (2) from (1),

i.e $=(2a - 3b + 4c)-(4a - 3b + 2c)$

$=2a - 3b + 4c-4a+3b-2c$

$=-2a+2c$

So, Taking $4a - 3b + 2c$ from $2a - 3b + 4c$ is $-2a+2c$

Therefore, Option 1 is correct.

2a-3b+4c-(4a-3b+2c)
=2a-3b+4c-4a+3b-2c
=-2a+2c
