Synthetic division And the Remainder theorem
stealth61 [152]
The remainder theorem says that if x-c is a factor of a polynomial p(x), then the remainder upon dividing \dfrac{p(x)}{x-c} is 0 so that there exists a lower degree polynomial q(x) as the quotient:

\dfrac{p(x)}{x-c}=q(x)

Using the fact that x-2 is a factor, you can find a quadratic q(x) which is easy to factorize further.

Synthetic division yields

q(x)=4x^2+4x-8

which can be factored further as

4(x^2+x-2)=4(x+2)(x-1)

So,

f(x)=4x^3-4x^2-16x+16=4(x-2)(x+2)(x-1)

The roots are then x=-2,1,2.

Answer:

Net\ Worth = \$2800

Step-by-step explanation:

Net worth is calculated using;

Net\ Worth = Assets - Debts

In this question, we have:

Laptop = \$1200 --- 2 years ago

Laptop = \$700 --- presently

Car = \$2900

Debt = \$800

Only the current worth of the laptop will be considered;

So, we have:

Assets = Laptop + Car

Assets = \$700 + \$2900

Assets = \$3600

Net\ Worth = Assets - Debts

Net\ Worth = \$3600 - \$800

Net\ Worth = \$2800
