Polynomials Ep. 3 - Adding Polynomials - 5:42
Since the function outside of the SECOND set of brackets is a positive you can simply remove the brackets and collect like terms.
LIKE TERMS: terms that have the same variable (letter) as well as the same exponent. When adding the like terms, simply add the numbers in front and keep the variable (letter) the same (i.e. 3x+5x = 8x)
x, 7x, 9x, -3x are like terms with one another. 6x^2 is NOT a like term with the previous examples because of the exponent 2 found with the variable x.
