x2-8x=-6
Add ((1/2)8)2 to both sides (add 16 to both sides):
x2-8x+16=10
Factor the left side:
(x-4)2=10
Take the square root of both sides
x-4 = ±√(10)
Make two equations because of the plus or minus:
x-4 = √(10) and x-4 = -√(10)
Add four to both sides (works for both equations):
x = 4+√(10) and x = 4-√(10)
x=3
If: x^2 -8x = -12 then x^2-8x+12 = 0 and so x = 2 or x = 6
3 - x = 8x = 3 - 8x = - 5
It's not possible to tell without another equation that supposedly represents the same line; it's only when you have two or more "comparisons" that you can establish consistency or inconsistencies.
X= -1/4. Y= -2/5. ( -.25, -0.4 )
x=3
If: x^2 -8x = -12 then x^2-8x+12 = 0 and so x = 2 or x = 6
3 - x = 8x = 3 - 8x = - 5
-1/2
To simplify the expression 5x - (-3x), you can rewrite it as 5x + 3x since subtracting a negative is the same as adding a positive. This simplifies to 8x. So, the result of 5x - (-3x) is 8x.
Change all signs, from -7 + 8x + 41 = 90 to +7 - 8x - 41 = -90
64x2-80x+25 = (8x-5)(8x-5) when factored

Y-8x plus 9y equals 10y-8x.
the answer of √8x+16-3x=0 is x= 0.447213595 = +/- 0.447(to 3 decimal places) if I'm not mistaken
