Question

12x^3y^4 - 40x^4y^3
I am having trouble with this one...
Factoring

Answer 1

Look at the like terms and find the greatest common factor.

What is GCF of 12 and 40?

What is the GCF of x^3 and x^4 ?

What is the GCF of y^4 and y^3 ?

Answer 2

4?
x^2
and y^3??

Answer 3

check the middle one again.

Answer 4

x^3 - Thats what I think

Answer 5

So, 4x^3y^3 is GCF

Answer 6

Correct. So the GCF is: 4x^3y^3. Factor this out. Then divide each expression by 4x^3y^3 and enclose them inside parenthesis.

Answer 7

12x^3y^4 - 40x^4y^3 = 4x^3y^3 * ( ? - ? )

Answer 8

ok, here goes.
4x^3y^3 (3xy - 10 xy)

Answer 9

check each division again. 12x^3y^4 / (4x^3y^3) = 3y (not 3xy).
check the other one too.

Answer 10

4x^3y^3 (3y - 10 x)

Answer 11

correct.

Answer 12

OMG!! you made this seem so easy! lol Thank you

Answer 13

You are welcome.
