Look at the picture.
The angle y° and 71° are Supplementary Angles. Therefore y° + 71° = 180°.
The sum of measures of these three angles of any triangle is invariably equal to 180°.
Therefore we have the equation:

Answer:
The factor form of given expression is (x-4)(x-2i)(x+2i).
Step-by-step explanation:
The given expression is
It can be written as
According to the rational root theorem, all possible rational roots are in the form of
Where, a₀ is constant term and is leading coefficient.
Since the value of f(x) is 0 at x=4, therefore 4 is a root of the function and (x-4) is a factor of given expression.
Use synthetic method to find the remaining factors.
Therefore the factor form of given expression is (x-4)(x-2i)(x+2i).
