[ Explanation ]
- Simplify: -0.8b + 4.1c - (-3.2b) - 0.1c
-----------------------------------
-0.8b + 4.1c + 3.2b - 0.1c
-0.8b + 3.2b + 4.1c - 0.1c
- Add Similar Elements: -0.8b + 3.2b = 2.4b
2.4b + 4.1c - 0.1c
- Add Similar Elements: 4.1c - 0.1c = 4c
2.4b + 4c

To simplify this fraction, multiply the entire fraction by the conjugate of the denominator. The conjugate of a square root and a number being added to it would be the number <em>subtracted </em>from the square root. In other words, the conjugate of
would be
.
Applying that information to our fraction shown here, the conjugate of the denominator would be
. We will multiply both the numerator and denominator of our original fraction by this expression to obtain our answer, as shown below.



Our answer is
.
