Question

An expression is shown below.

(3x² + 2x − 5) − (5x² − 4x + 1)
A)-2x² +6x-6
B)-2x² - 2x - 4
8x²+6x-6
D) 8x² - 2x - 4

Answer 1

Result of
`\tt{}(3 {x}^(2) + 2x - 5) - ( {5x}^(2) - 4x + 1)` is
`\tt{} - {2x}^(2) + 6x - 6.`

Explanation:

`\tt{}(3 {x}^(2) + 2x - 5) - ( {5x}^(2) - 4x + 1)`

`\tt{} {3x}^(2) + 2x - 5 - {5x}^(2) + 4x - 1`

`\tt{} - {2x}^(2) + 6x - 6`
