Find values of a and b that make the following equality into identity:
x−1/(x+1)(x−4) = a/x+1 + b/x−4

The value of a and b in given expression must be respectively so that given equality becomes identity.

Need to find the value of a and b in following expression so that following equality will become identity.

  ------- eqn 1

Lets Simplify Right hand Side first,

On multiplying both sides by (x+1)(x-4) we get

On comparing coefficient of x and constant term separately, we get

a + b = 1 and 4a - b = 1

On adding the two equations we get

a + b + 4a - b = 1 + 1

=> 5a = 2

=>

So the value of a and b in given expression must be so that given equality becomes identity.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
