Question

Find the remainder when x4-a2x2+3x-a is divided by x+a

Answer 1

x + a = 0

x = -a

$p(x) = {x}^{4} - {a}^{2} {x}^{2} + 3x - a$

$p( - a) = {x}^{4} - {a}^{2} {x}^{2} + 3x - a$

$= { - a}^{4} - {a}^{2} ( { - a}^{2} ) - 3a - a \\ = { - a}^{4} + {a}^{4} - 4a \\ = - 4a$

Answer 2

✓Step by step process :

if we wanted to know what is the reminder if divide x+a to the polynomial , we have to do first as

x+a=0

x= -a

now put this value of x in polynomial and you will get the answer

as

=(-a)^4 -a^2(-a)^2 +3(-a) -a

= -4a

I hope you understand the solution.
