The system of equations and
Solving for in gives
Is there a way to simplify equation ?
Because at the end I arrive at
and can't proceed. Need to get typical form of square equation .
The solution for c is or .
For what real values of the parameter do the common solutions of the following pairs of simultaneous equations became identical?
(g) , Ans. or .
The process is to solve for , then to substitute that into second equation. From that we get and . Delta being we can get parameter.
and i got lost...
