Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer: x = 3 or x = -1

The domain values are: x=0, 2, -1, 4, -2
When x=0
When x=2,
When x=-1
When x=4
When x=-2
2. The given function is
When x=3,
Similarly,
Answer: 15 Times
Step-by-step explanation: It's 15 Times because if you add all of the other rolled times together you'll get 60 and 75-60=15.
Answer:
B
Step-by-step explanation:
It is B because every number, x, you plug in 5x-3, it is y.
