Answer:
2/6561
Step-by-step explanation:
Geometric sequence formula :
where an = nth term, a1 = first term , r = common ratio and n = term position
given ratio : 1/3 , first term : 2 , given this we want to find the 9th term
to do so we simply plug in what we are given into the formula
recall formula :
define variables : a1 = 2 , r = 1/3 , n = 9
plug in values
a9 = 2(1/3)^(9-1)
subtract exponents
a9 = 2(1/3)^8
evaluate exponent
a9 = 2 (1/6561)
multiply 2 and 1/6561
a9 = 2/6561

Split the second term into two terms
2{x}^{2}+3x-2x-32x2+3x−2x−3
2 Factor out common terms in the first two terms, then in the last two terms<span>x(2x+3)-(2x+3)<span>x(2x+3)−(2x+3)</span></span>
3 Factor out the common term 2x+32x+3<span><span>(2x+3)(x-1)<span>(2x+3)(x−1)</span></span><span>
