Locating zeros of polynomial function: determine the number of complex zeros

In a previous question about this function, you determined that there were two (2) real zeros, near -1.4 and +3.4. (q: question/11280846)

Since this is a 4th degree polynomial, there are 4 zeros total, so two complex zeros.

The factorization is

... f(x) = (x² -2x -5)(x² -x +1)

The latter factor has zeros at 0.5±i·0.5√3.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
