Question

check whether x+3 is a factor of the polynomial x³-x²+11x+69​

Answer 1

divide it u will get the answer

if the remainder is 0 means it is the factor of the equation u have given but if other than 0 means not a factor of the equation given by u

please mark me as brainliest and please follow me

Answer 2

p(x)=x³-x²+11x+69

Divisor=x+3

take x=(-3) By remainder theorem

p(-3)=(-3)³-(-3)²+11(-3)+69

p(-3)= -27-9-33+69

p(-3)= -36-33+69

p(-3)= -69+69

p(-3)=0

remainder= 0

By factor theorem x+3 is the factor of x³-x²+11x+69
