  2. 18 then plus 3 is 21
  3. so 18 plus 21 is 39
  4. Then the greatest number is 18x2=36

Find all the zeroes of the equation. x4 – 6x2 – 7x – 6 = 0
NeX [460]

Answer:

-2, 3,  -0.5 + 0.866i,   -0.5 - 0.866i.

Step-by-step explanation:

As the last term is -6 , +/- 2 , +/- 3 are possible zeroes.

Try 2:-

(2)^4 - 6(2)^2 - 7(2) - 6 = -28 so  2 is not a zero.

3:-

(3)^4 - 6(3)^2 - 7(3) - 6 = 0 so 3 is a zero.

(-2)^4 - 6(-2)^2 - 7(-2) - 6 =  0 so -2 is also a zero.

Divide the function by (x +2)(x - 3),  that is  x^2 - x - 6

gives  x^2 + x + 1

x^2 + x + 1

So we have x^2 + x + 1 = 0

x =  [-1 +/- √(1^1 - 4*1*1)] / 2

= -1 + √(-3) / 2 , - 1 - √(-3)  / 2.

= -0.5 + 0.866i, -0.5 - 0.866i

What is 19/25 as decimal
Radda [10]
Well first we need to find how we can turn 25 into 100 
Well one way would be to multiply by 4 
25 x 4 = 100 

Since we multiplied the bottom number by 4 we should multiply the top number by 4. 

So..
19 x 4 = 76

So our new fraction is..
 76 
-----
100

Now we can easily turn this into a decimal. 
76/100 = 0.76 

Answer = 0.76 

Good Luck! :)
