Step-by-step explanation:
Answer:
There is no solution to 
Step-by-step explanation:
That's because when you use 
that means you want the absolute value, which makes all numbers that are put into those to lines positive. The absolute value is used when you aren't using negative numbers or working with something that can't be in the negative. Think about it like a number line but the negative side to the left doesn't exists.
If you try plugging in -11 which would normally make that -6, it will change it from -11 to positive 11.
Anything you put into absolute value will be positive. So you won't be able to get -6 with this formula because you'll always be adding and to get -6 you need to subtract.
Answer:
(0, 3)
Step-by-step explanation:
(0, 3) is the following is the midpoint between (3, 2) and (-3, 4)
This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i
