Which polynomial equations have -i as one of their roots? a) x3 + 5x2 - 20 = 0 b) x3 - x2 + x - 1 = 0 c) x3 + 3x2 + x + 3 = 0 d) x3 - 2x2 + x - 2 = 0 e) x3 - 6x2 - 16x + 96 = 0

Equation B, C and D have -i as one of their roots        

Step-by-step explanation:

We have to check the polynomial equations that have -i as one of the roots.

Thus, we have to check whether

A)

B)

C)

D)

E)

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree
