Which two values of x are roots of the polynomial below? 3x2 - 3x + 1
Inga [223]

For this case we have the following polynomial:

3x^2 - 3x + 1

Applying the formula of the resolvent we have:

x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}

Substituting values we have:

x=\frac{-(-3)+/-\sqrt{(-3)^2-4(3)(1)}}{2(3)}

Rewriting we have:

x=\frac{3+/-\sqrt{9-12}}{6}

x=\frac{3+/-\sqrt{-3}}{6}

x=\frac{3+/-i\sqrt{3}}{6}

Therefore, the roots of the polynomial are given by:

x=\frac{3+i\sqrt{3}}{6}

x=\frac{3-i\sqrt{3}}{6}

Answer:

The values of x that are roots of the polynomial are:

x=\frac{3+i\sqrt{3}}{6}

x=\frac{3-i\sqrt{3}}{6}

mash [69]
The radius is half the diameter. So do 4.1 times 3.14 for the circumference. :)
