so did you get what I solved the answer is D ok
x^2-9x-6=0
Use the quadratic formula to get (9+sqrt(105))/2 or (9-sqrt(105))/2
Think of 2 times 2
You would duplicate 2 two times
8 times 8 is 64
6 times 6 is 36
It’s kind of just adding an integer (any number) to the integer that is stated after it
Use all the top to multiply by it
Then divide by the buttom.
7-20+3-1*5+3-1-72=
-13 +3-5+2-72=
= - 85
