x + 3x
1x + 3x
4x
Simplify the following expression:
2x + 3x + x
5x
2x + 3x + x
2x + 3x + 1x
5x
3 (2x + 5)
6x + 15
5x + 3 = 18

(But don't forget to actually COME BACK to it)
You can combine 4a and 3b
False
Two terms need to be alike (same variable, same exponent) in order to combine them
Simplify the following expression:
4x2 + 9x2 - 14m
4x2 + 9x2 - 14m
13x2 - 14m
-5 (2x - 4)
-10x + 20
7x - 6 = 22
x = 4
True or False:
You shouldn't eliminate test questions on a virtual test.
FALSE!
You can combine 6p2 and 3p2
True! both terms have the same variable and same exponent
6p2 + 3p2
9p2
Simplify the following expression:
6x2 + 5m - 3x2 + 2m
6x2 + 5m - 3x2 + 2m
6x2 - 3x2 + 5m + 2m
3x2 + 7m
- (m - 3)
-m + 3
5x + 3 + 7x = 27

False
Simplify means to combine as many like terms as possible
Simplify the following expression:
x2 - 3x2 + 4y + 6x2
6x2 - 3x2 + 1x2 + 4y
3x2 + 1x2 + 4y
4x2 + 4y
3x (8 - 2)
18x
-3 (x - 5) = 66
x = -17

You cannot combine a term that has an exponent with one that does not
Simplify the following expression:
5m + 4m2 - 3m + 5m2 - 18
5m + 4m2 - 3m + 5m2 - 18
5m - 3m + 4m2 + 5m2 -18
2m + 4m2 + 5m2 -18
2m + 9m2 -18
7x (2x + 3) + 5x
14x2 + 26x
4x - (6x - 1) = 17
x = -8
