Question

Which is the correct first line for dividing the function

Answer 1

Given function is f(x) = x³ -12x +16.

We can write it as x³ +0x² -12x +16.

We need to write the numbers in order from left to right, so it would be {1, 0, -12, 16}.

Given factor is x -2 = 0, that means x = 2. So we need to divide the numbers by 2.

So correct way to divide the function would be 2 L 1, 0, -12, 16.

Hence, option C is correct.

Answer 2

Answer: The answer is the third option.

Step-by-step explanation:

1. To divide the polynomials given above, $f(x)=x^{3}-12x+16$ by $(x-2)$, you must complete the polynomial with the missing term $0x^{2}$:

2. Now, you need to write the coefficients of the polynomial:

1  0  -12  16

 3. You must write the denominator and solve for $x$ in the deminator to find the number that you need to write in the box to make the division:

$x-2=0\\x=2$
