How to write the equation
The equation of the polynomial is written using the formula
f(x) = a (x - p) (x - q) (x - r).....
Where p, q, r, ... are the zeros or roots of the equation
For equal zeros or roots say x = 4 twice
In factored form we have
f(x) = (x - 4)²
For unequal zeros or roots say x = 4 and x = 3
In factored form we have
f(x) = (x - 4) (x - 3)
