Question

HELPS WHATS THE ANSWER

Answer 1

`3x^2+2x-3`

Explanation:

`3x^2 - 4x - 8 - ( 2x - 5 )`

`3x^2- 4x - 8 - 2x + 5`

`3x^2 +4x - 8 - 2x + 5`

`3x^2+2x-3`

`Solution = 3x^2+2x-3`

Answer 2

A

Explanation:

(f - g)(x)

= f(x) - g(x)

= 3x² + 4x - 8 - (2x - 5) ← distribute parenthesis by - 1

= 3x² + 4x - 8 - 2x + 5 ← collect like terms

= 3x² + 2x - 3 → A
