Answer:

{6x}^{3}  +  {9x}^{2}  - 18x + 3

Step-by-step explanation:

1. Expand by distributing sum groups.3x( {2x}^{2}  + 5x - 1) - 3( {2x}^{2}  + 5x - 1)

2. Expand by distributing terms.

{6x}^{3}  +  {15x}^{2}  - 3x - 3( {2x}^{2}  + 5x - 1)

3.Expand by distributing terms.

{6x}^{3}  +  {15x}^{2}  - 3x - ( {6x}^{2}  +  15x - 3)

4. Remove parentheses.

{6x}^{3}  +  {15x}^{2}  - 3x -  {6x}^{2}  - 15x + 3

5. Collect like terms.

{6x}^{3}  +  {15x}^{2}  -  {6x}^{2} ) + ( - 3x - 15x) + 3

6. Simplify.

{6x}^{3}  +  {9x}^{2}  - 18x + 3

Thus. the answer is,

{6x}^{3}  +  {9x}^{2}  - 18x + 3
