Evaluate the integral by completing the square and using trigonometric substitution. √ √x² (Express numbers in exact form. Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) √√√x²- - 4x - 21 dx Incorrect - 4x 21 dx = – 25 In (x − 2 + √√ −21 + x² − 4x + ¹/√−25+ (x − 2)² (x − 2) + C
