Answer 2

D. -7x² + 6x - 7

Explanation:

Given expression:

`(-2x^2+3x-5)-(5x^2-3x+2)`

Distribute the negative sign to each term inside the second parentheses, remembering that:

`\boxed{( - )( - ) = +}\;\; \textsf{and}\;\;\boxed{( - )( + ) = -}`

`-2x^2+3x-5-5x^2+3x-2`

Collect like terms:

`-2x^2-5x^2+3x+3x-5-2`

Combine like terms:

`-7x^2+6x-7`

Therefore, the expression that is equivalent to the given expression is:

`\large\boxed{-7x^2+6x-7}`
