Answer:
76
Step-by-step explanation:
recall that for a quadratic equation in the form
ax² + bx + c = 0, the discriminant is given by 
discriminant, D = b²- 4ac
we are given the following:
-6x² + 2x + 3 = 0, 
comparing this with the general equation above, it is clear that, 
a = -6, b = 2 and c = 3, 
substituting these into our equation for discriminant:
D = b²- 4ac
= 2² - 4(-6)(3)
= 4 + 72
= 76
 
        
             
        
        
        
200 x 150 = 30,000 to purchase
200 x 175 = 35,000 when selling
35000 - 30000 is 5,000 capital gain
        
                    
             
        
        
        
- Multiply (-2x-4) by -5:
[(-5)(-2x) + (-5)(-4)] +5x - 4 = -29
= 10x+20+5x-4=-29
- Combine Like Terms:
(10x+5x) + (20-4) = -29
15x+16=-29
- Subtract 16 from each side
15x+16 -16 = -29 -16
15x = -45
x = -3
