Question

When P(x) = x - 1 is divided by (x - a),  the remainder is 2, find the value of a
​

Answer 1

Answer:

a=3

Step-by-step explanation:

Using Remainder Theorem

It states that putting the zero of divisor in the divident(polynomial), we get the remainder of the polynomial

Note that here remainder is given...

Zero of x-a is a.

So,

P(a)=a-1=2

Therefore,

a-1=2

a=2+1

a=3.
