GIVING BRAINIEST IF CORRECT!!<br><br> Factor x^4 - 16 completely

ioda

Answer:

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

Step-by-step explanation:

Hello!

We can use the difference of square method.

<h2>Difference Of Squares (DOS)</h2>

The formula for the DOS is $(a + b)(a - b) = a^2 - b^2$

It is a simple way to factor polynomials.

The criteria:

Has to begin and end with a perfect square
The operation has to be subtraction

<h3>Factor:</h3>

$x^4 - 16$

Begins with a perfect square (x² * x²) and ends with a perfect square (4 * 4)

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

Warning! Watch out, there may be another DOS!

$x^2 - 4$ is another DOS

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

The x² + 4 is not a DOS because the operation is addition.

The final factored form is $(x^2 + 4)(x + 2)(x - 2)$

If you invested $500 at 5% simple interest for 2 years, how much interest do you earn? Show work and answer in

givi [52]

Answer:

$50

$30.88

I will invest in simple interest as the interest there is more.

Step-by-step explanation:

If I invested $500 at 5% simple interest for 2 years, then the interest that I will get will be given by the formula

$I = P \times \frac{rt}{100}$ , where P is the invested principal, r is the APR and t is the time in years.

So, in our case, $I = 500 \times \frac{5 \times 2}{100} = 50$ dollars. (Answer)

Now, if I invest $500 at 3% compound interest compounded monthly for 2 years.

Now, using the formula of compound interest we have

$I = P(1 + \frac{r}{n \times 100} )^{tn} - P$ , where r is the APR and n is the number of times in a year the principal is compounded.

In our case, $I = 500(1 + \frac{3}{12 \times 100} )^{2 \times 12} - 500 = 30.88$ dollars. (Answer)

Therefore, I will invest in simple interest as the interest there is more. (Answer)
