Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
The answer is going to be 87.5%
Sum is add
sum of x and 2 means x+2
nothing to it
Answer:
<u>With parentheses:</u>

Hope this helps! :)
