Answer 2

Answer:-

Your Answer Is 1.

Explanation:-

The remainder can be find out by 2 methods:-

• Long Division Method.

• Remainder Theorem.

1) By Long Division Method:-

[Done In the ATTACHMENT].

2) By Remainder Theorem:-

Since x³ - ax² + 1 is divided by x-a so by Remainder theorem we get,

↦ x - a = 0.

↦ x = a.

So The value of x is a.

By putting the vakue of x we get,

↦ x³ - ax² + 1.

= (a)³ - a(a)² + 1.

= a³ - (a × a²) + 1.

= a³ - a³ + 1.

= 0 + 1.

= 1 = Remainder.

Therefore the remainder is 1.
