Question 244921: Please help me with this problem. The question is below
write third-degree polynomial equation with real coefficients and the roots 3,3+i. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! write third-degree polynomial equation with real coefficients and the roots 3,3+i.
-------------
If the coefficients are Real Numbers, 3-i must also be a root.
--------------
Equation:
y = (x-3)(x-(3-i))(x-(3+i))
---
y = (x-3)((x-3)+i)((x-3)-i)
---
y = (x-3)[(x-3)^2+1]
---
y = (x-3)(x^2-6x+10)
---
y = x^3-6x^2+10x-3x^2+18x-30
---
y = x^3-9x^2+28x-30
