Answer:
x = -3, 0, 2
Step-by-step explanation:
=> x³ + x² - 6x = 0
=> x(x² + x - 6) = 0
=> x² + x - 6 = 0 or x = 0
=> x² + 3x - 2x - 6 = 0 or x = 0
=> x(x + 3) - 2(x + 3) = 0 or x = 0
=> (x + 3)(x - 2) = 0 or x = 0
=> x = - 3 or x = 2 or x = 0
Answer:
The discriminant is 40
Step-by-step explanation:
First, rewrite the equation as 
so that the equation is in the form of 
. Thus, the discriminant is 
. This tells us that since the discriminant is greater than 0, then there are 2 real solutions.

Alright, so 3f-g=4 and f+2g=5.
3f-g=4
f+2g=5
Multiplying the first equation by 2 and adding it to the second, we get 7f=13 and by dividing both sides by 7 we get f=13/7. Since f+2g=5, then we can plug 13/7 in for f to get 13/7+2g=5. Next, we subtract 13/7 from both sides to get 2g=3+1/7=22/7 (since 3*7=21 and 21+1=22). DIviding both sides by 2, we get 22/14=g. Plugging that into f/39g, we get (13/7)/(22*39/14)
= (13/7)/(858/14)
= (13/7)*(14/858)
=182/6006
= 91/3003 (by dividing both numbers by 2)
= 13/429 (by dividing both numbers by 7)
= 1/33 (by dividing both numbers by 13)
