What is the least possible degree of a polynomial that has roots -5,1 + 4i, and -4i? 3
2
5
4​

Without any extra conditions, the answer could be 3, and the simplest polynomial with the given roots would be

(x + 5) (x - (1 + 4i )) (x + 4i )

= x ³ + 4x ² + (11 - 4i ) x + 80 - 2i

If the polynomial is supposed to have only real coefficients, then any complex roots must occur along with their complex conjugates:

(x + 5) (x - (1 + 4i )) (x - (1 - 4i )) (x + 4i ) (x - 4i )

= x ⁵ + 3x ⁴ + 23x ³ + 133x ² + 112x + 1360

and then the degree would be 5.

he sells x mount because thats eqivilqant to the maz and then divided into quarters

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
