Only one cause it takes 180 degrees<span> to make a triangle so all you do is add it up</span>
Step-by-step explanation:
substitute x= -1 into the equation to get the remainder
remainder= -2
the remainder is not a fraction
no, it is not a factor since its remainder is not zero
Answer:

Step-by-step explanation:
1) In this question we've been given "a", the leading coefficient. and two roots:

2) There's a theorem, called the Irrational Theorem Root that states:
If one root is in this form
then its conjugate
. is also a root of this polynomial.
Therefore

3) So, applying this Theorem we can rewrite the equation, by factoring. Remembering that x is the root. Since the question wants it in this expanded form then:
