What does it mean to solve over the complex numbers?

Over the complex numbers, every polynomial (with real-valued coefficients) can be factored into a product of linear factors. We can state this also in root language: Over the complex numbers, every polynomial of degree n (with real-valued coefficients) has n roots, counted according to their multiplicity.

How do you solve a complex conjugate?

You find the complex conjugate simply by changing the sign of the imaginary part of the complex number. To find the complex conjugate of 4+7i we change the sign of the imaginary part. Thus the complex conjugate of 4+7i is 4 – 7i. To find the complex conjugate of 1-3i we change the sign of the imaginary part.

How do you find the complex number of a quadratic equation?

Imaginary or complex roots will occur when the value under the radical portion of the quadratic formula is negative. Notice that the value under the radical portion is represented by “b2 – 4ac”. So, if b2 – 4ac is a negative value, the quadratic equation is going to have complex conjugate roots (containing “i “s).

How to use algebra solve for X?
