9x^(2) - 6xy + y^(2) - 81
9x^(2) - 81 + y^(2) - 6xy
9(x^(2) - 9)+ y(y - 6x)
9(x-3)(x + 3) + y(y - 6x)
9x^(2)
What else can I help you with?
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
What is 9x plus 27 equals -81?
9x + 27 = -81 Subtract '27' from both sides 9x = - 108 Divide both sides by '9' x = -12
How do i simplify and identify any x-values for which the expression is undefined -2x 2-9x 4x 2-81?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared", "cubed". There appear to be several expressions: -2x, 2-9x, 4x and 2-81 all of which are defined.
Square root x plus 3 equals 12?
X = 81 sqrt(X) + 3 = 12 ( subtract 3 from each side ) sqrt(X) = 9 (square both sides ) X = 81 ( the square root of 81 is 9 )
What x what equals 81?
9x9=81
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
What is 9x squared minus 6xy plus y squared minus 81 factored as?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
What is 9x squared minus 6xy plus y squared minus 81?
The answer? There is no "answer" There cannot be an answer because they are all different. In order to make calculations, the variables have to be the same. x squared, xy, y squared are the variables, and none of them match. Therefore your "answer" must look like this: 9x squared - 6xy + y squared - 81. Hope I Helped :D
How would you factor 9x2 - 6xy plus y2 - 81?
9x^2-6xy+y^2 = (y-3x)^2 (y-3x)^2-81 -> ((y-3x)+9)((y-3x)-9)
How do you factor 9x2-6xy y2-81?
(3x - y)(3x - y) - 81
How do you factor 9xx-6xy yy-81?
(3x - y + 9)(3x - y - 9)
How do you factor 9x2-6xy plus y2-81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 (since the first three terms make a perfect square = (3x - y - 9)(3x - y + 9) since the expression now is a difference of two squares.
How do you factor 4x squared minus 36x plus 81?
(2x - 9)(2x - 9) or (2x - 9)2
What is 9x squared plus 9x divided by 45x squared plus 81?
(9x)2 +9x/(45x)2 +81= 9+9x/86
How do you factor the expression x squared minus 81?
x2-81 = (x-9)(x+9)
How do you factor 81 minus 25u squared?
(9 - 5u)(9 + 5u)
How do you factor 81-36U squared?
