I disagree as the value will always be positive due to the absolute value symbol.
Answer:
x = 4±sqrt(19)
Step-by-step explanation:
Assuming you meant x^2 -8x = 3
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 = 16
Add this to each side
x^2 -8x +16= 3+16
The number inside the square term is the coefficient divided by 2
(x-4)^2=19
Take the square root of each side
sqrt((x-4)^2=±sqrt(19)
x-4 = ±sqrt(19)
Add 4 to each side
x-4+4 = 4±sqrt(19)
x = 4±sqrt(19)
Hello from MrBillDoesMath!
Answer: Choice D, 3 (x^2+1) + 2
Discussion:
f(g(x)) = f (x^2 + 1) * Note: I think that "x2" was meant to be x^2
= 3 * (x^2 +1) + 2 =
(3 x^2 + 3) + 2
Factor 3 from each term:
= 3 (x^2 _1) + 2
which is choice "d".
Thank you,
MrB
