Solve the quadratic equation numerically (using tables of x- and y- values). x2 + 7x+ 12 = 0
x= -1 or x = -1
x= -3 or x = -3
x = -4 or x = -3
x = 2 or x = -1

x2 + 7x + 12 = 0

Step-by-step explanation:

(x + 4) (x + 3)

x + 4 = 0 or x + 3 = 0

x = - 4 or x = - 3

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
