Question

Solve equation x(x-2)(x+3)=0

Answer 1

Hint:

if AB = 0, then A = 0 or B = 0

Answer 2

So this means that if

x(x-2)(x+3)=0

then

x=0, x-2=0, or x+3=0

Answer 3

Solve each equation for x to find your three answers

Answer 4

I got it to (x^2-2x)(x+3)=0

Answer 5

no need to do that

Answer 6

I just don't know how to distribute it

Answer 7

it's valid of course, but you're going backwards

Answer 8

that's the way my school wants me to do it though

Answer 9

really? that's odd...

Answer 10

oh wait

Answer 11

do you see what I wrote above? that's the best way to do it

Answer 12

yea, I understand

Answer 13

how do you get the result then?

Answer 14

alright great

Answer 15

solve each equation for x

Answer 16

I need a solution set

Answer 17

ok

Answer 18

x-2=0

x = ???

Answer 19

x+3=0

x = ???

Answer 20

2

Answer 21

good, and what else

Answer 22

aren't I only suppose to get 2 answers for a solution set?

Answer 23

wait wait wait

Answer 24

no, in this case, you'll get 3

Answer 25

if I get it to (x^2-2x)(x+3)=0, can I just divide the first one by 2 and get (x-2)(x+3)=0?

Answer 26

no need to do that though

Answer 27

so the answer is x=2 and x=-3?

Answer 28

there's one more

Answer 29

0?

Answer 30

bingo

Answer 31

x(x-2)(x+3)=0

x=0, x-2=0, or x+3=0

x=0, x=2, or x = -3

Answer 32

woo!!

Answer 33

thank you :3
