To factor by grouping, you group up the 1st 2 terms together and the last 2 terms together and then factor those pieces.
(x^3 + x^2) + (x + 1)
x^2(x + 1) + 1(x +1) - now factor out the (x + 1)
(x + 1)(x^2 + 1) - final answer
Answer:
4092
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
4
← is the n th term
with a = 4 and r = 2
The sum to n terms of an arithmetic series is
=
, thus
= 
= 4(1024 - 1) = 4 × 1023 = 4092
