Answer:
yes, people denote the set of rational numbers by. however, is not closed under the operation of taking square roots.
![4x^{3}+43x^2+30x](https://tex.z-dn.net/?f=4x%5E%7B3%7D%2B43x%5E2%2B30x)
First in factoring, you must find out what is common in the whole equation
![x(4x^2+43x+30)](https://tex.z-dn.net/?f=x%284x%5E2%2B43x%2B30%29)
Now, make 2 sets of parentheses and "split up" the rest of the equation
Try to experiment which numbers work out
We are not subtracting anything so both parentheses are positive
![x(4x+3)(x+10)](https://tex.z-dn.net/?f=x%284x%2B3%29%28x%2B10%29)
Therefore, the factored version of
![4x^3+43^2+30x](https://tex.z-dn.net/?f=4x%5E3%2B43%5E2%2B30x)
is

Answer:
The answer is 12 and 4
Step-by-step explanation:
1st equation: -x-(-y)=8
2nd equation: (-x)(-y)=48
-x-(y)=8
-x+y+8
y=x+8
-x(x+8)=48
-x^2-8x=48
Multiply -1
x^2+8x=-48
x^2+8x+48=0
(x+12)(x-4)=0
x=-12
x=4
Check:
-(-12)-(4)=8
12-8=8
8=8
(-12)(-4)=48
48=48
