Answer:
A
Step-by-step explanation:
The domain does not exist when the denominater of an equation is zero. So in this case if x was -2 and we added 2 the denominator would be zero, and that value does not exist in the domain. Hope this helps!
Answer:
I have no idea. Umm maybe ask your mom. Or dad do either of them know math?
U could try to email your teacher.
Step-by-step explanation:
I'm going to assume that f(x) = x^2. f(x)*g(x):
x^2(x - 8) --> Apply the distrubutive property
x^3 - 8x^2
The product of f(x) - x^2 and g(x) = x - 8 is x^2 - 8x^2
Answer:
7/45
Step-by-step explanation:
First of all simplify
That becomes
-5+25x - 8x -2= -4x -8x
Then bring together values with similarities
-5 -2 = -4x -8x -25x +8x
-7 = -45x
x = 7/45
We must solve the quadratic equation
4x² + 98 = 0
using the quadratic formula.
First simplify the equation by dividing both sides by 2:
2x² + 49 = 0
Identify the coeficients:
a = 2
b = 0
c = 49
Calculate delta:
Δ = b² - 4ac
Δ = 0 - 4.2.49
Δ = 0 - 392
Δ = -392
Now let's apply the quadratic formula:
x = (-b ± √Δ) / 2a
x = (-0 ± √-392) / 4
x = ± 14√2i / 4
x = ± 7√2i / 2
So
x' = -7√2i / 2
x'' = 7√2i / 2
Answer: the roots are x' = -7√2i / 2 and x'' = 7√2i / 2
