In earlier classes, we have studied linear equations in one and two variables and quadratic equatiions in one variable. We have seen that the equation x2+1=0 has no real solution as x2+1=0 gives x2=-1 and square of every real number is non-negaive. So, we need to extend the real number system to a larger system so that we can find the solution of the equation x2=-1. In fact, the main objective is to solve the equation ax2+bx+c=0, where D=b2-4ac<0, which is not possible in the system of real numbers.
