Adding & Subtracting Polynomials

When Adding & Subtracting Polynomials

Add or subtract the coefficients of like terms
Like Terms: Same variable AND power
Write answers in standard form
Standard Form: list terms in order of their exponents from highest to lowest. Example: 6x - 2x²+3 should be written as -2x²+6x+3

Multiple Choice

What is the standard form of the polynomial,

7x - 125 - 6x⁴ + 14x²

125 + 7x - 14x² +6x⁴

6x⁴ -14x² - 7x +125

125 + 14x² + 7x - 6x⁴

-6x⁴+ 14x² + 7x - 125

Multiple Choice

What is the standard form of the polynomial,

9x² + 5x + 27 + 2x³

27 + 5x + 9x² + 2x³

9x² + 5x + 2x³ + 27

9x² + 5x + 27 + 2x³

2x³ + 9x² + 5x + 27

Multiple Choice
