Remember Like terms: Have the same variable and exponent
14x2 12x2 7g 81g
5c 45c 7w3 34w3

Match the like terms
• 18x• 15y2
• 2m• 7z3
• 9w4
• 17y2
• 3m• 5z4

You can only add/ subtract like terms!!!14x + 5x = 19x
12y – 4y = 8y
4c + 5y = NO!!
![Page 6: 2.2 strat. Warm UP!!!! find the sum Remember Like terms: Have the same variable and exponent 14x 2 12x 2 7g 81g 5c 45c 7w 3 34w 3.](https://reader035.fdocuments.us/reader035/viewer/2022070411/56649f505503460f94c72f4a/html5/thumbnails/6.jpg)
Rules for Exponents:When you add/subtract like terms you keep the exponent the same
3x2 + 5x2 = 8x2
14x2 – 7x2 = 7x2
![Page 7: 2.2 strat. Warm UP!!!! find the sum Remember Like terms: Have the same variable and exponent 14x 2 12x 2 7g 81g 5c 45c 7w 3 34w 3.](https://reader035.fdocuments.us/reader035/viewer/2022070411/56649f505503460f94c72f4a/html5/thumbnails/7.jpg)
Rules for exponents:When you multiply terms you multiply the
coefficients and ADD the exponents.
4x2 ( 8x3 + 5x2) = 32x5 + 20x4
2x( 15x2 + 5x + 4) = 30x3 + 10x2 + 8x
