Step-by-step explanation:
Regression Equation has the firm of,
Y = aX + b
please refer to my attachment for a and b.
So prepare table with columns of Y, X sq(x),......
then work out a and b according.
Finally sub a and b into the equation Y = aX + b
If you add them all up it would be 6.
Answer:
3
2x^9 = 1
3x^6 = 2
- x - 20 = 3
The answer is (x-6) squared
