Answer 2

Answer = 3

Step-by-step explanation:

solution:>

to find remainder:-

x³-3x²+6x-15 when divided by x-3.

according to the remainder theorem

put x-3=0 => x= + 3 in the given polynomial the

remainder is. found.

=>>>>> (3)³ - 3 (3)²+6×(3)-15

= +27-27+18-15

= 3

to find quotient and remainder:-

x³-3x²+6x-15

= x³-3x²+6x-18 +3

= x²( x-3) + 6( x-3) +3

= (x²+6) (x-3) + 3

divident=quotient× divisor + remainder

comparing we have

quotient= x²+6

remainder= 3
