Answer:
Step-by-step explanation:
To answer this question, we will work backwards.
We know that a factor is 4+3i. This means that:
Hence, we will eliminate the imaginary and convert this into standard form.
First, distribute the negative:
Add 3i to both sides:
Square both sides:
Expand:
Add 9 to both sides:
Hence, our quadratic equation is:
Notes:
We will get the same equation if we use (4-3i). This is because we square the (3i) regardless of its sign, making it positive.
