Question
Let a,b,c such that then ,?
Hint:
Take LCM on RHS, then equate the coefficients by comparing LHS and RHS and find the value of a,b, c
The correct answer is:
Given :
Taking LCM on RHS
Simplifying
Cancelling denominators on both side
Further simplifying
Equating coefficients by comparing LHS and RHS
Multiplying by 5 in equation 3 and subtracting equation 2 from it, we get
Multiplying by 6 in equation 3 and subtracting equation 1 from it, we get
Multiplying by 2 in equation 4 and subtracting equation 5 from it, we get
Multiplying by 6 in equation 3 and subtracting equation 1 from it, we get
2b + 4c = 10

3b + 4c = 6
______________
 b = 4
b = 4
Substituting value of b, we get c = 9/2 and a = 1/2
