( 1 3-6 x-9 x² d x ) is equal to

Options

  1. A( ⁻¹ ( 3 x+1 2 )+C )
  2. B( ⁻¹ ( 3 x+1 6 )+C )
  3. C( 1 3 ⁻¹ ( 3 x+1 2 )+C )
  4. D( ⁻¹ ( 2 x+1 3 )+C )

Correct answer

C. ( 1 3 ⁻¹ ( 3 x+1 2 )+C )

Step-by-step solution

Given that, ( 1 3-6 x-9 x² d x ) Since, ( 3-6 x-9 x²=4-(3 x+1)² ) So, ( 1 4-(3 x+1)² d x ) ( = 1 3 ⁻¹ ( 3 x+1 2 )+c )
