6c2 + 2.5d – d + 2c2 – 3d
To simplify the expression 6c^2 + 2.5d - d + 2c^2 - 3d, we can combine like terms.
Combining the c^2 terms: 6c^2 + 2c^2 = 8c^2
Combining the d terms: 2.5d - d - 3d = -1.5d
Therefore, the simplified expression is 8c^2 - 1.5d.
To simplify the expression 6c2 + 2.5d - d + 2c2 - 3d, we can combine like terms.
- The terms 6c2 and 2c2 are like terms because they both have the variable c raised to the power of 2. To combine them, we add their coefficients: 6 + 2 = 8. So, the simplified expression so far is 8c2.
- The terms 2.5d, -d, and -3d are also like terms because they all have the variable d. To combine them, we add their coefficients: 2.5 + (-1) + (-3) = -1.5. So, the simplified expression so far is -1.5d.
Putting it all together, the simplified expression is:
8c2 - 1.5d
