How can I tell, when doing synthetic division, if the binomial is<br> a FACTOR of the dividend?

Alecsey [184]

If you get 0 as the last value in the bottom row, then the binomial is a factor of the dividend.

Let's say the binomial is of the form (x-k) and it multiplies with some other polynomial q(x) to get p(x), so,

p(x) = (x-k)*q(x)

If you plug in x = k, then,

p(k) = (k-k)*q(k)

p(k) = 0

The input x = k leads to the output y = 0. Therefore, if (x-k) is a factor of p(x), then x = k is a root of p(x).

It turns out that the last value in the bottom row of a synthetic division table is the remainder after long division. By the remainder theorem, p(k) = r where r is the remainder after dividing p(x) by (x-k). If r = 0, then (x-k) is a factor, p(k) = 0, and x = k is a root.

Veronika [31]

Answer:

2 × h

Step-by-step explanation:

h = b ÷ 2 (multiply both sides by 2)

2 × h = b ÷ 2 × 2

2 × h = b

b = 2 × h

Colby adds 1 2/3 cups of flour to his mixing bowl and then realizes he put too much.He takes 1/4 cup of flour back out of the bo

galben [10]

Answer:

The quantity of flour need by Colby's recipe is $1\frac{5}{12}$ cups.

Step-by-step explanation:

Given: Colby adds $1\frac{2}{3}$ cups of flour to his mixing bowl and then realizes he put too much.He takes $\frac{1}{4}$ cup of flour back out of the bowl.

We have to find the quantity of flour need by Colby's recipe.

The quantity of flour need by Colby's recipe = Number of flour cups Colby added - number of flour cups Colby taken out.

that is,

Number of flour cups Colby added = $1\frac{2}{3}=\frac{5}{3}$

Number of flour cups Colby taken out = $\frac{1}{4}$

The quantity of flour need by Colby's recipe = $\frac{5}{3}-\frac{1}{4}$

taking LCM, we get, LCM(3,4) =12

The quantity of flour need by Colby's recipe = $\frac{20-3}{12}$

The quantity of flour need by Colby's recipe = $\frac{17}{12}=1\frac{5}{12}$

Thus, The quantity of flour need by Colby's recipe is $1\frac{5}{12}$ cups.
