Terms
Exponents: a number placed above and after another
number or variable a number used to show the power the prior number or variable will be raised to.
or
Exponents
Variables: a quantity that is represented by a symbol
or letter assumes any given value or set of values.
(a, b, c, p, x, z, y, m, n)
or
Variables
Constants: A number or quantity placed before another
quantity A number multiplying another quantity Also known as a coefficient
or
Constants
Like terms: Terms where the constants and exponents
are alike.
****What is the solution?****7n³
Look for terms that are the same2n + 5n² - n – 3n²
2n – n are alike 5n² - 3n² are alike
Add or Subtract the constants
2n-n = (1)n 5n² - 3n² = 2n²
List in order by exponents
Final answer: 2n² + n
1) 8x + 6n 2) 6p + p3) 3n – 3n²4) 7z – 6z + 2z³
5) Identify the terms, variables, constants, and exponents in problems 2 and 4.
6) Why can’t some of these terms be combined?
Answer Box:1.8x + 6n2.7p3.3n – 3n²4.Z + 2z³
