Answer:
x = ± 
It didn't insert but just look up the quadratic formula.
x = ± root [(b²-4ac]/2a]
Answer:
The only possible answer that is correct is the first one, x = -4.
Step-by-step explanation:
Simplify the given inequality as much as possible, and then substitute each of the given x values one by one to determine which is in the solution set.
9(2x + 1) < 9x - 18 becomes 18x + 9 < 9x - 18, which, if reduced by dividing all four terms by 9, becomes 2x + 1 < x - 2.
Simplifying further, we get x < - 3. The only possible answer that is correct is the first one, x = -4. -4 < -3 is true.
-1 would be your answer. f(0) = -4. f(1) = f(0)+3 so f(1) = -1
