Anything with 3 degree's: Cubic
Anything with 4 degree's: Quartic
 
        
             
        
        
        
P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
 
        
                    
             
        
        
        
Let x = cost of the dishwasher. 
The amounts the children are paying are:
Mark =20% = 1/5, so  1/5x
Sorin = 75
Raymond = 1/4x
Stephanie = 75
Kristin = 1/3x
Add them together:
x = 1/5x + 1/4x + 1/3x + 75 + 75
 x - ( 1/5x + 1/4x + 1/3x ) = 150
Rewrite fractions with common denominator:
 x - ( 12/60x + 15/60x + 20/60x ) = 150
 60/60x - 47/60x = 150
 13/60x = 150
 x = 150/1 • 60/13
 x = 9000/13
 x = 692.31
The total cost of the dishwasher is $692.31
Now calculate the amount each child pays:
Mark = 1/5 x = 692.31/ 5 = $138.46
Sorin = $75.00
Raymond = 1/4 x = 692.31 / 4 = $173.08
Stephanie = $75.00
Kristin =  1/3 x = 692.31 / 3 = $230.77
 
        
             
        
        
        
59×2=118 cost of bill.
59÷4=14.75 for the other 4 if the bill was 118 assuming Thomas pays half.
or...59 ×5=295
assuming they all pd 1/5 of the bill
