Combine Like Terms Simplify Expressions

Simplify the following expression:
(5x⁴ - 3x + 8x²) - (8x⁴ - 7x²)

• 13x⁴ - 3x + 1x²

• -3x⁴ + 15x² - 3x

• -3x⁴ - 1x² + 3x

• 13x⁴ + 15x² - 3x

Simplify by combining like-terms.

45y + 6y - 30y

• 81y

• 9y

• 21y

• 81

Combine like-terms.

9c + a + 2c + (-5c) + 7a

• 6c + 8a

• 16c + 8a

• 13ac

Combine Like Terms:

12y - 8 + 3y - 2

• 9y + 6

• 9y - 10

This is an example of __________ __________.

• distributive property

• combining terms

• math thingy

The expression is: 4 ( 3x - 6 - 2x)

The next step is: 12x - 24 - 8x

What is the final, simplified expression?

• That's it. It is simplified.

• 20x - 24

• -12x - 8x

• 4x - 24

Distribute and then Combine Like Terms: 2(4x + 7) + 3x

• 8x + 14

• 8x + 7

• 11x + 7

• 11x + 14

Distribute then combine like terms

2(9x - 2) + 2

• 18x - 11

• -52x - 50

• -20 + 50x

• 18x - 2

Distribute then combine like terms

6(n - 9) + 9

• 27n - 60

• -30 + 9n

• -26 + 9n

• 6n - 45
