Question

What is the remainder of (2x3 − 18x + 5) ÷ (x − 3)?

-5

5

2

3

Answer 1

@Peaches15 can you help?

Answer 2

4

Answer 3

x-5=0 solve for x
and the substitute x in this 2x^3 − 18x + 5 equation for its value

Answer 4

or you can apply synthetic division

Answer 5

it should be -5

Answer 6

-5 is wrong i got it wrong the last time i tried it

correction:
x-3=0

Answer 8

would it be 3?

Answer 9

ok clarify your equation
2x3 or 2x^3

Answer 10

solve for this x-3=0
then x=3 put value of x in equation you will get answer

Answer 11

sorry its 2x^3

Answer 12

yep so now substitute al x for 3\[\huge\rm 2(3)^3-18(3)+5= ??\]

Answer 13

it's 5

Answer 14

so 2-18+5=-11

Answer 15

lol nah put value of x

Answer 16

you will get 54-54+5=5

Answer 17

no substitute x for 3
just replace x

Answer 18

oh okay i think i get it now

Answer 19

x for 3\[\huge\rm 2(\color{reD}{3})^3-18(\color{reD}{3})+5= ??\]

Answer 20

when you are given like that divided by x-5 or x-3 etc then just put it equal to zero and get value of x put this value in equation you will get your answer

Answer 21

good job Nnesha

Answer 22

or if you want to apply synthetic division then you need to write highest degree to smallest
0 for 0x^2 it's not in the equation but we still have to write highest degree to smallest
x^3,x^2 and then x
