Identify the GCF of the polynomial 6xy - 30x2y4. 6xy 6 6xy - 30x2y4. 5xy
I got A
Start with the coefficient. Then move to the x term. Then the y term. Why do you say A?
I'm not good at gcf.....
It's simple. c: You just need to find what both of the term share. Let's start with the coefficients: 6 and 30 6 can be broken down into 1*6 or 2*3, those are factors of 6. 30 can be broken down into a few things, but 5*6 is the important one, We can factor out a 6 out of 30 --> 30 = 6(5) Therefore, the greatest common factor between 6 and 30 is 6. It's the biggest number that can be shared between them.
So, we can rewrite the expression by factoring out the 6. 6xy - 30x^2y^4 = 6(xy - 5x^2y^4)
so it's C?
:3 Next is the x factor. Look at the factored form: 6(xy - 5x^2y^4) How many x's can be shared between the two terms in the parentheses. And nooooo. ;-;
:( ...
|dw:1406465396860:dw| So, if you look at this drawing, the first term has one x. The second term has 2 x's. The greatest common factor would always be the least amount of variables. The first term only has 1 x it can share. So, we can factor out the x. 6x(y - 5xy^4)
