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:

$Assets = Laptop + Car$

$Assets = \$700 + \$2900$

$Assets = \$3600$

$Net\ Worth = Assets - Debts$

$Net\ Worth = \$3600 - \$800$

$Net\ Worth = \$2800$
