Why is x-5 not a factor of -3x^4 +15x^3 -x +5

Step-by-step explanation:

according to factor theroem,

if x-a is a factor then then f (a)=0

lets try putting x value in equtaion it must come 0 x=5

(-3×5)^4+(15×5)-5+5

=472500

we dont get here answer 0 so it is not factor of it

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
