I don't know these answers. Can you help me? Greatest common factor in 1.6y^2-9y+18.

2.4x^2y-7xy
3. 30a^3b-40ab^3
4. factor out greatest common factor in 4x^2-12x+20
5. x^4y-6x^3y-6x^2y
4 and 5 are factoring out the greatest common and 1-4 is finding the greastest common factor.

Certainly! Let's go through each question step by step:

1. To find the greatest common factor (GCF) of 1.6y^2 - 9y + 18, you need to identify the common factors among all the terms. In this case, the GCF can be found by factoring out any common factors that all the terms share:

1.6y^2 can be written as (1.6)(y^2), and 9y can be written as (9)(y). However, 18 doesn't have any common factors among the other terms.

Therefore, the GCF of 1.6y^2 - 9y + 18 is simply (1.6)(y), which can be written as 1.6y.

2. To find the GCF of 2.4x^2y - 7xy, you need to factor out the common factors that both terms share. Both terms have an x and a y:

2.4x^2y can be written as (2.4)(x^2)(y), and 7xy can be written as (7)(x)(y).

Therefore, the GCF of 2.4x^2y - 7xy is (x)(y), which can be written as xy.

3. To find the GCF of 30a^3b - 40ab^3, you need to identify the common factors among both terms. Both terms have a 10, an a, and a b:

30a^3b can be written as (10)(3)(a^3)(b), and 40ab^3 can be written as (10)(4)(a)(b^3).

Therefore, the GCF of 30a^3b - 40ab^3 is (10)(a)(b), which can be written as 10ab.

4. To factor out the greatest common factor in 4x^2 - 12x + 20, you need to identify the highest common factor among all terms. In this case, the GCF is 4 since all terms are divisible by 4:

4x^2 can be written as (4)(x^2), 12x can be written as (4)(3)(x), and 20 can be written as (4)(5).

Therefore, the GCF of 4x^2 - 12x + 20 is 4.

5. To factor out the greatest common factor in x^4y - 6x^3y - 6x^2y, you need to find the highest common factor among the terms. In this case, the GCF is simply x^2y:

x^4y can be written as (x^2)(x^2)(y), 6x^3y can be written as (6)(x)(x^2)(y), and 6x^2y can be written as (6)(x^2)(y).

Therefore, the GCF of x^4y - 6x^3y - 6x^2y is (x^2)(y), which can be written as x^2y.

I hope this explanation helps you understand how to find the greatest common factor and factor out common factors in expressions! Let me know if there's anything else I can assist you with.

>) Well dumb chess weakling, all i know iz the answer to 30a^3b-40ab^3 4 iz 10ab >)

>( that's it! >(

>)MWA HAHAHAHAHA >) CHESS WEAKLING!

Greatest common factor for 39,6

The greatest common factor is the highest number (or variable, or both) that you can divide each part by.

1. 3
4. The GCF is 4, so when you divide each part by 4 you get x^2-3x+5
Try the rest, and submit them if you want them checked.

Thanks alot. I got an A on my assignment.
