Question

How do I do this step by step?!

Answer 1

`2x^(2)` +
`2x` +
`2`

Explanation:

1. In the expression: C - 3D, we plug in the values of C and D

2. So we get the expression:
`(2x^(2) + 5x -1) - 3(x - 1)`

3. Then we simplify this even more:
`(2x^(2) + 5x -1) - (3x + 1)` by multiplying 3 to the numbers in the parentheses

4. Now we can remove the parentheses:
`2x^(2) + 5x - 1 - 3x + 3`

5. Now we can put the like terms next to each other:
`2x^(2) + 5x - 3x + 3 - 1`

6. FINALLY we simplify:
`2x^(2) + 2x + 2`
