Answer:

${6x}^(3) + {9x}^(2) - 18x + 3$

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,

${6x}^(3) + {9x}^(2) - 18x + 3$
