Question 182149: 1. can polynomials have coefficients which are not real numbers?
2. can a linear polynomial ever have a zero or root which is not real?
3.what's the method to find zeroes of a cubic polynomial?

1. can polynomials have coefficients which are not real numbers?
Ans: Sure, for example (sqrt(2))x^2 + (sqrt(5))x + 3
------------------------------------------------------------
2. can a linear polynomial ever have a zero or root which is not real?
Ans: For y = mx + b the root is always -b/m. If b or m are
not Real the root will not be Real.
Ex: y = sqrt(2)x + 3 has root -3/sqrt(2)
----------------------------------------------
3.what's the method to find zeroes of a cubic polynomial?
Ans: Google will find you the forms taht can be used but graphing
with a scietific calculator is the fastest way to find Real roots
of a cubic.
