The partial fraction decomposition of 28/ x^2−4 can be written in the form of f(x)/ x−2 + g(x)/ x+2, where f(x)? where g(x)?

The value of f(x) is - 7  , and  The value of g(x) is 7   .

Step-by-step explanation:

Given as :

The partial fraction fraction decomposition of

i.e  = +  

Or,    =

Or, 28 = f(x) × (x - 2) +  g(x) × (x + 2)

Now, put x = 2

So , 28 = f(x) × (2 - 2) +  g(x) × (2 + 2)

Or, 28 = 0 + 4 × g(x)

∴ g(x) = = 7

Now, put x = - 2

So , 28 = f(x) × ( - 2 - 2) +  g(x) × ( - 2 + 2)

Or, 28 = - 4 × f(x) + g(x) × 0

∴ f(x) = = - 7

Hence The value of f(x) is - 7  , and  The value of g(x) is 7   .  Answer

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
