How do you do x ^4-4? What is the x values?

VladimirAG [237]

We know that
A difference of two perfect squares (A² - B²) can be factored into (A+B) • (A-B)
 then
x ^4-4--------> (x²-2)*(x²+2)
(x²-2)--------> (x-√2)*(x+√2)
x1=+√2
x2=-√2

the other term
(x²+2)=0-> x²=-2-------------- x=(+-)√-2

i is called the imaginary unit. It satisfies i² =-1
Both i and -i are the square roots of -1
√ -2 =√ -1• 2 = √ -1 •√ 2 =i • √ 2 
The equation has no real solutions. It has 2 imaginary, or complex solutions.
x3= 0 + √2 i
x4= 0 - √2 i 

the answer is

the values of x are
x1=+√2
x2=-√2
x3= 0 + √2 i
x4= 0 - √2 i

What is 6% of 20? Please answer as soon as possible.

Gekata [30.6K]

TO get 6% of 20 we have to write 6% in decimal (or fraction if u want but decimal allows u to multiply it easier i think)
6%=0.06= $\frac{6}{100}$
Now u have to mulitply 0.06 times 20
0.06*20=1.2 - its the result

Janice Went to five different stores in the mall, she spent an average of $30 at each store. After visiting just the first four

777dan777 [17]

Based on Janice average, she spent $50 at the last store.

Let a, b, c, d, e represent the money spent on the five stores respectively.

Since she spent an average of $30 at each store, hence:

(a + b + c + d + e) / 5 = 30

(a + b + c + d + e) = 150

She spent $100 on the first four stores, hence:

a + b + c + d = 100

(a + b + c + d + e) = 150

100 + e = 150

e = 50

Hence based on Janice average, she spent $50 at the last store.
