(Number 12) thanks!

Conjugate Pairs Theorem - P(x)= 0 is a polynomial equation with real coefficients and the
complex number a+bi (b0) is a root, then a-bi is also a root.
10.
Create a polynomial equation with real coefficients that has 2 and 1-i as roots.
Descartes's Rule of Signs - Suppose P(x)=0 is a polynomial equation with real coefficients and
with terms written in descending order.
The number of positive real roots of the equation is either equal to the number of
variations of sign of P(x) or less than that by an even number.
The number of negative real roots of the equation is either equal to the number of
variations of sign of P(-x) or less than that by an even number
Discuss the possibilities for the roots to :
2x - 5x² – 6x+4 = 0
12.3x*-5x' -x² - 8x+4=0
