Is x – 3 a factor of the polynomial p(x) = 2x^4– 9x^3 + 15x^2 – 22x + 12, and for what reason?
a) yes, because p(3) is equal to 0.
b) yes, because p(–3) is equal to 0.
c) no, because p(3) is not equal to 0.
d) no, because p(–3) is not equal to 0.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
