**Class 12 Maths Important questions on Chapter 7 Integral with Solutions for term 2 CBSE Board 2021-22**

Ans. The given function is

Let t = 3x

dt/dx = 3

dt = 3dx

Substituting 3dx by dt,we have

We know

Substituting t=3x,we have

Ans. The given function is

2x – xยฒ = -[xยฒ -2x +1 -1]= -[(x – 1)ยฒ -1] =1 – (x – 1)ยฒ

Substituting this value in the function

Ans. The given function is

**Q4. Evaluate**

9 + 8x – xยฒ =-(xยฒ -8x -9) = -(**xยฒ -8x +4ยฒ** -4ยฒ-9)=-[(x -4)ยฒ -25] =**5ยฒ – (x -4)ยฒ**

Sustituting this value in the denominator

**Q5. Evaluate**

Ans. Let t = 7 – 4x

differentiating both sides

dt/dx = -4

dt = -4 dx

dx = -dt/4

Substituting this value in the function

**Q6. Evaluate**

Ans. The given function is

Ans. The given function is

Q8. Evaluate

Ans. The given function is

Q9. If x >a then evaluate

Ans. The given function is

Q10. Evaluate

Ans. The given function is

Let t = โx

tยฒ = x

2t.dt/dx = 1

dx = 2t.dt

Substituting these values ,we get

= 2t + C

Substituting the value t= โx

= 2โx + C

Q11.Evaluate

Ans. Let the given function is f(x)

Therefore given function is an even function

=2(e – 1)

=2e -2
