P(x) = x3 - 2x2 + 2x<br> What are the real and complex zeros of the equation
vesna_86 [32]

Given:

The polynomial is

p(x)=x^3-2x^2+2x

To find:

The real and complex zeros of the equation.

Solution:

We have,

p(x)=x^3-2x^2+2x

For zeros, p(x)=0.

x^3-2x^2+2x=0

x(x^2-2x+2)=0

x(x^2-2x+2)=0

x=0\text{ and }x^2-2x+2=0

The real value of x is 0. The equation x^2-2x+2=0 will give complex roots. Here, a=1, b=-2 and c=2.

Using quadratic formula, we get

x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(1)(2)}}{2(1)}

x=\dfrac{2\pm \sqrt{4-8}}{2}

x=\dfrac{2\pm \sqrt{-4}}{2}

On further simplification, we get

x=\dfrac{2\pm \sqrt{-1}\sqrt{4}}{2}

x=\dfrac{2\pm 2i}{2}

x=\dfrac{2(1\pm i)}{2}

x=1\pm i

Therefore, the real zero is 0 and the complex zeros are 1+i and 1-i.
