Please, share just ONE problem at a time.  Thanks.
<span>Solve 2x^2-12x+20=0:
Simplify this by dividing each term by 2:  x^2 - 6x + 10 = 0
Identify a, b and c:  a=1, b=-6 and c=10.  Then b^2=36.
Write out the solutions using the quadratic formula:
        6 plus or minus sqrt(36-40)
x = ---------------------------------------
                            2
sqrt(36-40) = sqrt(-4) = plus or minus i2
Then:
 
         6 plus or minus i2
x = --------------------------- (answer)

Remainder:

EXPLANATION
The given functions are 

and

We want to find the quotient and the remainder when f(x) is divided by g(x).
We perform the long division as shown in the attachment.
The quotient is 

The remainder is 
 
 
        
        
        
Answer:
8
2
0
2
8
Step-by-step explanation:
f(x)=2x^2
f(x)=y
y=2x^2
y=2(-2)^2
y=2(4)
y=8
y=2x^2
y=2(-1)^2
Y=2
Y=2X^2
y=2(0)^2
y=0
y=2x^2
y=2(1)^2
y=2
y=2x^2
y=2(2)^2
y=8
