Question 15
Integrationintegrate ∫(2x + 1)dx
- A.x2 + x + c
- B.x2 − x + c
- C.x2 + 2x + c
- D.x2 − 2x + c
Show the answer and explanation
Answer: A (x2 + x + c)
Explanation
∫2x dx = x² and ∫1 dx = x, so the result is x² + x + c.
integrate ∫(2x + 1)dx
Answer: A (x2 + x + c)
∫2x dx = x² and ∫1 dx = x, so the result is x² + x + c.
