Answer:
8√3.
Step-by-step explanation:
192 = 2 * 2 * 2 * 2 * 2 * 2 * 3
The square root of the multiple of the 6 2's is 2*2*2 = 8
so √192 = 8√3.
The other side is x^2+9
x^3-27/x-3= x^2+9
Answer:
x=-5 x=-4
Step-by-step explanation:
y=x^2 + 9x + 20
We need to factor the equation
What 2 numbers multiply to 20 and add to 9
4*5 = 20
4+5 =9
y=(x+5) (x+4)
To find the zero's we set the equation equal to zero
0= (x+5) (x+4)
Using the zero product property
x+5 = 0 x+4=0
x=-5 x=-4
