Answer:
−438°, -78°, 642°
Step-by-step explanation:
Given angle:
282°
To find the co-terminal angles of the given angle.
Solution:
Co-terminal angles are all those angles having same initial sides as well as terminal sides.
To find the positive co-terminal of an angle between 360°-720° we will add the angle to 360°
So, we have: 
To find the negative co-terminal of an angle between 0° to -360° we add it to -360°
So, we have: 
To find the negative co-terminal of an angle between -360° to -720° we add it to -720°
So, we have: 
Thus, the co-terminal angles for 282° are:
−438°, -78°, 642°
One is a linear and the other is a quadratic polynomial.
And (x+2) is indeed a factor.
You can rewrite it as (x+2)(3x-7)
