Step-by-step explanation:
- This is a polynomial, and every expression like y=p(x) , with p(x) a polynomial, is a function.
<u>Factoring:</u>
This equation cannot be factored because its roots are irrational (as shown by solving with the quadratic formula). Also, to factor a quadratic equation, you need to find a pair of numbers whose product is equal to the c term (-5) and whose sum is equal to the b term (-6). There is no pair of numbers which satisfies this, further showing that the equation cannot be factored.
<u>Quadratic Formula:</u>
The quadratic formula is x=.
First, you need to find the a, b and c terms of your equation. They are 1, -6, and -5 respectively.
Now, you must plug in to the equation and solve for x. You must do so twice, once with a plus sign in the numerator and once with a minus.
The answers are 3+√14 and 3-√14.
