Solve x^4-8x^2-9=0<br><br> Pls help
Softa [21]

Answer:

Step-by-step explanation: x can be 3, -3, i, or -i.

Explanation:

If you can't find the factoring by looking at this, simplify the equation.

let

x

2

=

y

to make things easier to see

Now we have

y

2

−

8

y

−

9

=

0

See it now?

We can factor into

(

y

−

9

)

(

y

+

1

)

Now substitute back in

x

2

for

y

.

(

x

2

−

9

)

(

x

2

+

1

)

Since

(

x

2

−

9

)

is a difference of two squares,

(

x

−

3

)

(

x

+

3

)

Now we have

(

x

−

3

)

(

x

+

3

)

(

x

2

+

1

)

x can be 3, -3 for the first two parts

x

2

+

1

=

0

can become

x

2

=

−

1

Taking the positive and negative root means

x

=

±

√

−

1

Thus

x

=

±

i

in addition to 3 and -3.

Ray planted a square garden that covers an area of 200ft squared. How many feet of fencing does he need to surround the garden?
Dafna11 [192]

Ray needs 56.4 feet of fencing to surround the garden.

Step-by-step explanation:

Given,

Area of square garden = 200 ft²

As the garden is in square shaped.

Let a be the one side of square

Area = a²

a^2=200

Taking square root on both sides

\sqrt{a^2}=\sqrt{200}\\a=14.1 \ft

For the measure of fencing, we will find the perimeter.

Perimeter = 4a

Perimeter = 4(14.1) = 56.4 ft

Ray needs 56.4 feet of fencing to surround the garden.

Keywords: square, area
