if, X²¹+21 is divided by X+1, find the remainder. plz help me i need the answer quick About the author Lydia

Answer: remiander = 21 Step-by-step explanation: x^21+21 gets divided by x+1 as x+1/x^21+21 x+1*x^20 = x^21 + x^20 +21, now remainder is x^20+21 then we multiply x+1*x^19= x^20+x^19+21 , now remainder is x^19 +21 then we go on and on till we get as remainder x^2+21 then the quotient will be x and then the the answer will be x^2+x+21 and then x divides x^2 and when 1*x , the remainder is 21 Reply

Answer:remiander = 21

Step-by-step explanation:x^21+21 gets divided by x+1 as

x+1/x^21+21

x+1*x^20 = x^21 + x^20 +21, now remainder is x^20+21

then we multiply x+1*x^19= x^20+x^19+21 , now remainder is x^19 +21

then we go on and on till we get as remainder x^2+21

then the quotient will be x and then the the answer will be x^2+x+21 and then x divides x^2 and when 1*x , the remainder is 21
