PLZ HELP ME!!!
AnnZ [28]

Answer:

A: 6x^2(x^8-16)

B: 6x^2(x^4+4)(x^2+2)(x^2-2)

Step-by-step explanation:

<u>A:</u>

Our expression is 6x^{10}-96x^2. We need to find some common factors. Clearly, we can see that both terms share the x² part, so we can definitely take that out:

6x^{10}-96x^2

x^2(6x^8-96)

Let's see if 96 is divisible by 6:

96 ÷ 6 = 16; since there's no remainder / the remainder is 0, we know 96 is divisible by 6, so we can also factor out 6:

x^2(6x^8-96)

6x^2(x^8-16)

Thus, the answer to part A is 6x^2(x^8-16).

<u>B:</u>

Look at the x^8-16 part of the above factored expression. Notice that it is a difference of squares (because x^8=(x^4)^2 and 16 = 4²), so we can write this as:

x^8-16

(x^4+4)(x^4-4)

Now take a look at the (x^4-4) part. Again, it's a difference of squares because x^4=(x^2)^2 and 4 = 2², so rewrite that as:

x^4-4

(x^2+2)(x^2-2)

Put it all together:

6x^2(x^4+4)(x^2+2)(x^2-2)

Thus, the answer to part B is 6x^2(x^4+4)(x^2+2)(x^2-2).

BaLLatris [955]

Answer:

I believe the wrong answer would be D because when you look at the children to childcare ratio it would be 8÷2=4 and 2÷2=1 making it 4:1. this means A is correct and D is not.
