Find the value of , if is a factor of in the following case:
Step 1: State the given data and the factor theorem
According to the factor theorem, let is a polynomial and is a real number, then is a factor of , if .
It is given that is the dividend.
And, is the divisor.
Let us put the divisor equal to zero.
Step 2: Apply factor theorem
If, is a factor of , then by the factor theorem,
Hence, the required value of is .
