Answer:
x² - 6x + 9
Step-by-step explanation:
(a - b)² =a² - 2ab + b²
a = x and b = 3
(x - 3)² = x² - 2*x*3 + 3²
= x² - 6x + 9
Answer:
Sequence will be 2, 14, 98, 686.
Step-by-step explanation:
Since we know in an geometric sequence the terms are in the form are
in which
a = first term
r = common ratio
n = number of term
Now from this expression we can all terms of the sequence
in which a = 2 and common ratio r = 7
The sequence will be

Or 2, 14, 98, 686
So the answer is 2, 14, 98, 686.
