Expert Answer:
If x ? p is a factor of a linear polynomial, then the solution of that polynomial is p.
Consider a linear equation in one variable as ax + b = 0
Dividing a (the coefficient of x) both sides; x + b/a = 0
That is x ( ?b/a) = 0
This means x ( ?b/a) is a factor ax + b.
So, the solution of the equation x ( ?b/a) is ?b/a
