When ever you are solving a quadratic it is good to know the amounts of answers that you will be looking for.
x^2 + ... + c - Can answer the question of how many answer are in a quadratic.
What ever the highest exponent is, represents the number of answers you will get.
If it is x^4, then you will get 4 answers.
When you take a square root you get to answers.'
You get a positive and a negative answer.
If a + square root of(b) is a root then a - square root of(b) is also a root.
If a + bi is a root then a - bi is also a root.
If you have an odd degree at least one root must be a real root.
The sum of the roots
- 2nd coeff/leading coeff
The product of the roots
- if even constant/leading coeff
- if odd contant/leadin coeff
MERRY CHRISTMAS
