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)

What is x-squared minus 8x equals negative 15?
x=3
What is x squared minus 8x equals negative 12?
If: x^2 -8x = -12 then x^2-8x+12 = 0 and so x = 2 or x = 6
What is 3 minus x equals 8?
3 - x = 8x = 3 - 8x = - 5
Is 4y minus 8x equals negative 16 consistent or inconsistent?
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.
What is the ordered pair for 8x minus 5y equals -2?
X= -1/4. Y= -2/5. ( -.25, -0.4 )
What is x-squared minus 8x equals negative 15?
x=3
What is x squared minus 8x equals negative 12?
If: x^2 -8x = -12 then x^2-8x+12 = 0 and so x = 2 or x = 6
What is 3 minus x equals 8?
3 - x = 8x = 3 - 8x = - 5
What does 2x2 minus 8x equals -8?
-1/2
What is 5x minus (negative 3x)?
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.
How do you change negative 7 in the problem negative 7 plus 8x plus forty one equals ninety to a positive?
Change all signs, from -7 + 8x + 41 = 90 to +7 - 8x - 41 = -90
How do you factor 64x to the second power minus 80x plus 25?
64x2-80x+25 = (8x-5)(8x-5) when factored
What is 8x squared minus 8x minus 16 in factorization form?
(4x-8)(2x+2)
What is x squared minus 8x plus 8y plus 32 equals 0 in standard parabola form?
7
Is 4y minus 8x equals negative 16 consistent or inconsistent?
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.
What is the square root of 8x squared plus 16 minus 3x equals 0?
the answer of √8x+16-3x=0 is x= 0.447213595 = +/- 0.447(to 3 decimal places) if I'm not mistaken
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
