Answer:
D) 20⁰
Step-by-step explanation:
EDF = 180-100=80⁰
EFD= 80⁰+80⁰=160⁰
180⁰-160⁰=20⁰
-x² - x + 6
First thing I would do is distribute out that negative. Your new problem is:
- (x² + x - 6)
Now, factor the inside. We need to find products of - 6 that when added together have a sum of positive 1. They are 3 and - 2.
- (x² + 3x - 2x - 6)
Group together and find your factors. I'm going to short cut and go right to them for the sake of space and time.
- (x + 3)(x - 2)
Your answer is Option B
I hope this helps you
