3x + 6y + 7z and 5x + - 4y + 9z
= 3x + 5x + 6y – 4y + 7z +9z
=8x + 2y + 16z
You can only add LIKE TERMS!
Like terms are terms which containthe same variable (s)
REMEMBER:
-4x3 + 6x2 - 8x -10 and 7x3 - 4x2 + 9x + 3
= 4x3 + 7x3 + 6x2 - 4x2 - 8x + 9x -10 + 3
= 3x3 + 2x2 + x -7
REMEMBER:You can only add
LIKE TERMS!
3x + 8b – 5 and 9y + 2a +7b
REMEMBER:You can only add
LIKE TERMS!
= 3x + 8b +7b -5 +9y + 2a
= 3x +15b +2a - 5
BOARD WORKAnswer the following. Upon finding the right answer, get the letter that corresponds the value of the right
answer and place it on the designated boxes.
1. (3a+5b+7c) + (8a-2b-9c) 2. (3x2 + 7x + 4) + (5x2 - 9x + 4) 3. (7x2 - x – 4) + (x2 - 2x -3) + (-2x2 + 3x +5) 4. (2m + 3n -5) + (5m – 6n +12) 5. (4x + 8y + 9z -7z + 5b) + (4b +5x + 7y + 3z + 2a)

"Can both fresh water and salt water flows from the same spring? Neither can a salt spring produce fresh
water."
James 3: 11-12
Fresh water and salt water cannot flow from the same spring.
Same with math, different variables cannot be added and be
united into one term.
I. Evaluate and add the polynomials
1. (2x + 5y – 6z) + (3x – 2y +9z)
2. (3x3 + 3x2 - 4x + 5) + (x3 - 2x2 + x – 4)
3. (11x2 - 4x - 8) + (6x2+ 2x + 3)
4. (x3 + 5x2 - 2x) + (x3 + 3x – 6) + (2x2 + x + 2)
5. (5w – 7x -3y + 12z) + (7w +9x + 6y – 10z)
II. For 3 points, state how polynomials are added.
