arrow_back Return to Using the Quadratic Formula to find Complex Roots
a
Let's use the quadratic formula to find the solutions.
We have a negative number under the root sign. Therefore, the solutions will be complex.
The solutions are and
b
Now multiply the solutions together, which gives This is a multiplication of two parentheses, with the only difference between them being a negative sign. That means it is a conjugate pair of binomials. Let's calculate its product.
The product of the solutions is
