Answer:
2x(2x²+x+1)
Dtep-by-step explanation:
f(x) = 9x³+2x²-5x+4
g(x) = 5x³-7x+4
f(x) - g(x)
= 9x³+2x²-5x+4 - (5x³-7x+4)
= 9x³+2x²-5x+4-5x³+7x-5
= 4x³+2x²+2x
= 2x(2x²+x+1)

the value of r of the geometric series n=11.3(0.8)n-1
General formula for nth term of any geometric series is
Here 'r' is the common ratio
a_1 is the first term of the series
Now we compare the given formula with general formula
Compare with
The value of r= 0.8
