Answer:

2x² + 6x - 4

Step-by-step explanation:

f(x) - g(x)

= 3x² + x - 3 - (x² - 5x + 1) ← distribute

= 3x² + x - 3 - x² + 5x - 1 ← collect like terms

= 2x² + 6x - 4

Answer:

f(x) - g(x) = 2x² - 4x - 2

Step-by-step explanation:

f(x) = 3x² + x - 3

g(x) = x² - 5x + 1

f(x) - g(x)

3x² + x - 3 - x² - 5x + 1

3x² - x² - 5x + x - 3 + 1

= 2x² - 4x - 2

f(x) - g(x) = 2x² - 4x - 2
