Solve for all values of x using the quadratic formula when the equation is x2 + 3x +2. use variables with proper assignments for a, b and c.

x =  [-3 +/- √(3^2 - 4*1*2) ]  /  2

=  [- 3 + √( 1)]  / 2 ,   [- 3 - √( 1)]  / 2

=  -2/2 ,  -4/2

=  [-1, -2}       answer

hope it you

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

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
