HELPS WHATS THE ANSWER

Answer 1

Answer:

$3x^2+2x-3$

Step-by-step 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

Answer:

A

Step-by-step 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
