Answer:

${8x}^(2) + 4x - 4$

Explanation:

1) Use foil method: (a + b ) (c + d) = ac + ad + bc + bd.

${10x}^(2)+6x-5x-3-(2x-1)(x - 1)$

2) Use foil method: (a + b ) (c + d) = ac + ad + bc + bd.

${10x}^(2) + 6x - 5x - 3 - ( {2x}^(2) - 2x - x + 1$

3) Remove parentheses.

${10x}^(2) + 6x - 5x - 3 - {2x}^(2) - 2x - x + 1$

4) Collect like terms.

$( {10x}^(2) - {2x}^(2) ) + (6x - 5x + 2x + x) + ( - 3 - 1)$

5) Simplify.

${8x}^(2) + 4x - 4$

Therefor, the answer is 8x² + 4x - 4.
