Question

If x + 2a is a factor of a^5 -4a^2x^3 +2x + 2a +3, then find the value of a.

Answer 1

Answer:

f(1) and f(−a) both are equal to 0 by factor theorem.

∴ f(1)=1+2+a+b=0 and f(−a)=−a

3

+2a

2

−a

2

+b=0

∴ a+b=−3 and −a

3

+a

2

+b=0

Thus, on solving two equations we get, a=−1 and b=−2
