Question

(-3c² + 2c² -с +6) + (-4c³ +x6 — 2c²-5) - (7c⁴ - 5c³ - с).​

Answer 1

(-3c²+2c²-с+6)+(-4c³+6-2c²-5)-(7c⁴-5c³-с) = -3c²+2c²-с+6-4c³+6-2c²-5-7c⁴+5c³+с = -7c⁴-4c³+5c³-3c²+2c²-4c²-2c²-c+6+6-5 = -7c⁴+c³-7c²-c+7

Answer 2

Let's simplify the given expression step by step:

Expression: (-3c² + 2c² - c + 6) + (-4c³ + x6 - 2c² - 5) - (7c⁴ - 5c³ - c)

First, let's simplify each of the individual terms within the parentheses:

1. (-3c² + 2c² - c + 6) = (-c² - c + 6)
2. (-4c³ + x6 - 2c² - 5)
3. -(7c⁴ - 5c³ - c) = -(-7c⁴ + 5c³ + c) = 7c⁴ - 5c³ + c

Now, substitute the simplified terms back into the expression:

(-c² - c + 6) + (-4c³ + x6 - 2c² - 5) + (7c⁴ - 5c³ + c)

Combine the like terms:

-4c³ + 7c⁴ - c² - 2c² - 5c³ + c - c + 6 - 5

Combine the coefficients of each term:

7c⁴ - 9c³ - 3c² + 6

So, the simplified expression is: 7c⁴ - 9c³ - 3c² + 6
