Question

Subtract the given polynomials using the vertical format.

Answer 1

Answer:

10C³-7C²+4C

7c³-(-3c³) -5c²-(+2c²) +2c-(-2c)

Answer 2

Answer:    10c^3 - 7c^2 + 4c

===========================================

Explanation:

The negative out front of the parenthesis will swap the sign of each term. That means -3c^3 becomes +3c^3, or simply 3c^3. The other terms in the parenthesis are handled the same way.

After distributing the negative through, we add straight down.

The 7c^3+3c^3 becomes 10c^3

Then we have -5c^2+(-2c^2) become -7c^2

Finally, 2c+2c simplifies to 4c
