okay so it really easy. EX: 6x + 4x^2 - 2x + 3x^2 - 7x^5

So basically 6x - 2x because both of them have x and are raised to the power of 1. While 4x^2 + 3x^2 go together because they are both raised to the 2nd power. While -7x^5 doesn't go with any terms because no terms are raised to the 5th power.

Step 2: Combine the coefficients.

5h + 11g + 1h - 8g.

(5 + 1)h + (11 - 8)g.

6h + 3g.

Step 1: Organize your like terms.

5x + 8x + 10x2 - 7x2 - 4x.

here is an example

2k - 2j when j=4&k=6 replace the variable with the given amount and solve the problem

eimsori [14]

Answer:

Step-by-step explanation:

first, plug in 6 for k. (it doesn't matter which value you plug in first; you can start with j or k, but i'm just starting with k since that is the variable that comes first in the expression)

2k - 2j => 2(6) - 2j

then plug in 4 for j.

2(6) - 2j => 2(6) - 2(4)

now your expression is 2(6) - 2(4). simplify by multiplying 2(6) and then -2(4) (again, it doesn't matter which one you multiply first, as long as you make sure that the minus sign between 2(6) and 2(4) gets attached to the 2 in 2(4).)

2(6) - 2(4) => 12 - 2(4)

12 - 2(4) => 12 - 8

subtract 8 from 12.

12 - 8 = 4

your answer is 4, therefore when j = 4 and k = 6, 2k - 2j = 4.

i hope this helps! have a nice day <3

Answer:

8x + 60

Step-by-step explanation:

4(x + 5) + 2(x - 10) + 2(x + 30)

= 4x + 20 + 2x - 20 + 2x + 60 (combine like terms)

= 8x + 60
