Math Problem Statement

Simplify -4c^2b^2 - 10cb^2 + 12cb^2 - 11c^2b^2 by combining like terms.

Solution

The problem asks to simplify the expression 4c2b210cb2+12cb211c2b2-4c^2b^2 - 10cb^2 + 12cb^2 - 11c^2b^2 by combining like terms.

Step 1: Group like terms

We have two types of terms:

  • Terms involving c2b2c^2b^2: 4c2b2-4c^2b^2 and 11c2b2-11c^2b^2.
  • Terms involving cb2cb^2: 10cb2-10cb^2 and 12cb212cb^2.

Step 2: Combine like terms

  1. Combine the c2b2c^2b^2 terms: 4c2b211c2b2=(411)c2b2=15c2b2-4c^2b^2 - 11c^2b^2 = (-4 - 11)c^2b^2 = -15c^2b^2
  2. Combine the cb2cb^2 terms: 10cb2+12cb2=(10+12)cb2=2cb2-10cb^2 + 12cb^2 = (-10 + 12)cb^2 = 2cb^2

Final Simplified Expression:

15c2b2+2cb2-15c^2b^2 + 2cb^2

The correct option from the choices is: 15b2c2+2b2c\boxed{-15b^2c^2 + 2b^2c}
