Expand. Your answer should be a polynomial in standard form. ( c ^2 − 6 ) ( 2c ^2 + 3c − 1 ) =

2c⁴ + 3c³ - 13c² - 18c + 6

Step-by-step explanation:

Step 1: Distribute the c²

2c⁴ + 3c³ - c²

Step 2: Distribute the -6

-12c² - 18c + 6

Step 3: Combine the 2 distributions

2c⁴ + 3c³ - c² - 12c² - 18c + 6

Step 4: Combine like terms

2c⁴ + 3c³ - 13c² - 18c + 6

e.
