# Writing polynomial functions

posted by .

How to write a polynomial function with the integral coefficients that have the following roots:

#1.) 0, -1/2, 6

#2.) + or - 5i

• Writing polynomial functions -

#1 x(x+ 1/2)(x-6) = 0
Multiply it out to get the (cubic) polynomial.

#2 (x- 5i)(x +5i) = 0
Multiply it out and remember that i^2 = -1

• Writing polynomial functions -

1,2,3
