Answer:
y = x - 8
Step-by-step explanation:
There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!
Looking at inputs 20 and 21, the outputs are 8 less than the inputs. Check the other inputs and notice that the same pattern holds up.
Answer:
Step-by-step explanation:
Here, the given expression is
Now, simplifying the brackets, we get
= 
Now, operate on the like terms.
= 
=
Hence, the given expression is simplified to the quadratic equation
