SOLVE x^4 − 15x^2 − 16 = 0 <br> What are the roots of the equation?

kakasveta [241]

Answer:

roots : 4, -4, i, -i

Step-by-step explanation:

This gets a bit tricky.

We have to substitude x^2 as u in this problem.

Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get

u^2 - 15u - 16 = 0

( u - 16) (u + 1)

U = 16

U = -1

<em>This is not the end of the problem. </em>

Now we have to substitute x^2 back to u.

x^2 = 16 --> we get the roots 4 and -4

x^2 = -1 --> we get the roots i and -i

tadah!

Marco has a piece of wood that measures 9 x 1/10 + 6 x 1/100 + 4 x 1/1000 how can this measurement be written as a decimal? you

spin [16.1K]

Answer:

The decimal number is 0.964

Step-by-step explanation:

we have

$9(\frac{1}{10})+ 6(\frac{1}{100})+4(\frac{1}{1,000})$

step 1

Multiply each fraction by the whole number

$(\frac{9}{10})+ (\frac{6}{100})+(\frac{4}{1,000})$

step 2

Convert each fraction in a decimal number

Remember

Move the decimal point to the left as many places as there are zeros in the factor.

Move the decimal point one step to the left (10 has one zero).

Move the decimal point two steps to the left (100 has two zeros)

Move the decimal point three steps to the left (1000 has three zeros)

$0.9+0.06+0.004$

step 3

Adds the number

$0.964$
