25 point for this question:

for which values of a and b the following is true for any real number x?

The values of a and b are and respectively.

Step-by-step explanation:

Given that

We solve this by partial fraction method.

Taking L.C.M. in the RHS, we get

To find the value of 'b', substitute x = 2. This would make 'a' vanish leaving an equation with 'b'.

Therefore, 2 - 4 = a(2 - 2) + b(2 + 9)

⇒ -2 = 0 + b(11)

Similarly, substitute x = -9 to find the value of 'a'.

⇒ -9 - 4 = a(7) + b(0)

.

Therefore, the values of 'a' and 'b'b are: =-13/7 and -2/11 respectively.

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!
