Options

Choose one · Correct answer highlighted

1/2( x + 1 ) x^2 + 2x + 5 + 2 | x + 1 + x^2 + 2x + 5 | + C Correct ( x + 1 ) x^2 + 2x + 5 + 1 2 | x + 1 + x^2 + 2x + 5 | + C ( x + 1 ) x^2 + 2x + 5 + 2 | x + 1 + x^2 + 2x + 5 | + C ( x + 1 ) x^2 + 2x + 5 -2 | x + 1 + x^2 + 2x + 5 | + C

Explanation

We can see that we verify 1/2( x + 1 ) x^2 + 2x + 5 + 2 | x + 1 + x^2 + 2x + 5 | + C by full calculation: use standard identity, substitute, simplify step
