Question

x^3-x^2+6x-a divided by x-a​

Answer 1

Answer:

The remainder when x3 - ax2 + 6x - a is divided by x - a is 5a.

Step-by-step explanation:

Step 1:

Put sor= underline o

x - a = 0

x = a

Step 2:

Let p(x) = x ^ 3 - a * x ^ 2 + 6x - a

Putting x = alpha

p(a) = (a) ^ 3 - a * (a) ^ 2 + 6(a) - a =a^ 3 -a^ 3 +6a-a

=5a.

Thus, remainder = p(a) = 5a
