## RD Sharma Solutions for Class 12 Chapter 19 – Indefinite Integrals Exercise 19.20

### Exercise 19.20 Page No: 19.106

Evaluate the following integrals: Solution:    Solution: ⇒ 1 = (A + B) x + (3A – 2B)

⇒ Then A + B = 0 … (1)

And 3A – 2B = 1 … (2)

Solving (1) and (2),

2 × (1) → 2A + 2B = 0

1 × (2) → 3A – 2B = 1

5A = 1

∴ A = 1/5

Substituting A value in (1),  Or I = log|(x – 2)/(x + 3)| + x + c Solution:     Solution:      Solution:      Hence, ### Access Other Exercises of RD Sharma Solutions for Class 12 Chapter 19 – Indefinite Integrals
