Factor x^4-5x^2+4 show your work

ch4aika [34]

Answer:

$(x+2)(x-2)(x+1)(x-1)$

Step-by-step explanation:

STEP 1: Rewrite $x^{4}$ as $(x^2)^2$ .

$(x^2)^2-5x^2+4$

STEP 2: Let $u=x^{2}$ . Substitute $u$ for all occurrences of $x^{2}$ .

$u^2-5u+4$

STEP 3: Factor $u^2-5u+4$ using the AC method.

$(u-4)(u-1)$

STEP 4: Replace all occurrences of $u$ with $x^2$ .

$(x^{2} -4)(x^{2} -1)$

STEP 5: Rewrite $4$ as $2^{2}$ .

$(x^{2}-2^{2})(x^{2}-1)$

STEP 6: Since both terms are perfect squares, factor using the difference of squares formula, $a^2-b^2=(a+b)(a-b)$ where $a=x$ and $b=2$ .

$(x+2)(x-2)(x^{2}-1)$

STEP 7: Rewrite $1$ as $1^{2}$ .

$(x+2)(x-2)(x^2-1^2)$

STEP 8: Factor.

$(x+2)(x-2)(x+1)(x-1)$

9. Suppose you take out a car loan for $9999 for 4 years at a 7.5% interest rate. What is your

Alekssandra [29.7K]

Answer:

The monthly payment is $241.76.

Step-by-step explanation:

Given : Suppose you take out a car loan for $9999 for 4 years at a 7.5% interest rate.

To find : What is your monthly payment ?

Solution :

The formula to find monthly payment is

$M=\frac{\text{Amount}}{\text{Discount factor}}$

Discount factor is $D=\frac{1-(1+i)^{-n}}{i}$

Substitute in the formula,

$M=\frac{A}{\frac{1-(1+i)^{-n}}{i}}$

$M=\frac{A\times i}{1-(1+i)^{-n}}$

where, A is the amount A=$9999

r is the rate =7.5%=0.075

$i=\frac{r}{12}=\frac{0.075}{12}=0.00625$

time t=4 years

Time in months $n=t\times 12=4\times 12=48$

Substitute all the values in the formula,

$M=\frac{9999\times 0.00625}{1-(1+0.00625)^{-48}}$

$M=\frac{62.49375}{1-(1.00625)^{-48}}$

$M=\frac{62.49375}{1-0.7415101}$

$M=\frac{62.49375}{0.25848}$

$M=241.76$

Therefore, the monthly payment is $241.76.
