Answer:
x = 0, - 2
Step-by-step explanation:
To find f(g(x)) , substitute x = g(x) into f(x)
f(x²) = 2x² + 1
To find g(f(x)) , substitute x = f(x) into g(x)
g(2x + 1) = (2x + 1)²
Then equating
(2x + 1)² = 2x² + 1 ← expand left side using FOIL
4x² + 4x + 1 = 2x² + 1 ( subtract 2x² + 1 from both sides )
2x² + 4x = 0 ← factor out 2x from each term on the left side
2x(x + 2) = 0
Equate each factor to zero and solve for x
2x = 0 ⇒ x = 0
x + 2 = 0 ⇒ x = - 2
solutions are x = 0, - 2
Let us assume the first part to be = x
Then
The second part will be = 2x
The third part will be = 3 * 2x
= 6x
Then we can get to the equation
x + 2x + 6x = 846
9x = 846
x = 846/9
= 94
So
The first part will be = 94
The second part will be = 2x
= 2 * 94
= 188
The third part will be = 6x
= 6 * 94
= 564
So the three parts are 94, 188 and 564.The second option of 846 = x + 2x + 6x is the correct option.
