Question

Can someone please check my work on this math question? please? I'll fan and give a medal!!

Answer 1

Solve the quadratic equation by factoring --
3x^3 – 12x = 0

Answer 2

@jim_thompson5910 can you please help me?

Answer 3

What quantity (represented by the product of a number and a letter) represents a common factor of the given quadratic equation?

If you can identify that, then please write out that common factor as the multiplier of whatever is left. correct format:

wx(y - z) = 0

Answer 4

Be 100% certain that you know what "common factor" means in this context.

Answer 5

so would the common factor be x?

Answer 6

@agent0smith could you please try to help me?

Answer 7

Look at the quadratic. What common factor can you take out of both terms?

Answer 8

3x?

Answer 9

Yes.

Answer 10

okay then what do I do?

Answer 11

Take out the common factor out of both terms

Answer 12

what do you mean? like 3x^3 becomes 3x and 12x becomes 3x?

Answer 13

No.

If you were factoring 5x^4 + 35x
you'd write it as
5x(x^3 + 7)

Answer 14

I'm not sure how I would write 3x^3 – 12x = 0

Answer 15

@agent0smith ?

Answer 16

Try it.

Answer 17

3x(x^3 – 12) like that?

Answer 18

You took an x out of 3x^3 though... and a 3 out of 12. Try again

Answer 19

what do you mean?

Answer 20

3(x^3 – 9) thats what I needed?

Answer 21

No... taking out a factor is like dividing. You're doing it as if it's subtraction.

Answer 22

so 3x(x^2 – 3x)

Answer 23

Not that either...

Answer 24

okay, then idk what you mean...

Answer 25

You'll need to review some basics on factoring.

Answer 26

okay, but I was trying to write it in the format that you did this one 5x(x^3 + 7)
