Factor 9x squared - 6xy plus y squared - 81?
Type your answer here... 81
Solve 27y plus 18x equals 21?
This can be interpreted as a line in 2d space. There are an infinite number of solutions. More than likely your real question is: "How can 27y + 18x = 21 be written in standard slope-intercept form?"Same as 9y + 6x = 7 (divide both sides by 3).Solve for y:9y = 7 - 6xy = (7 - 6x) / 9, ory = (-2/3)x + 7/9We now have an eaquation of a line: slope = -2/3, y-intercept = 7/9Paste -2/3x + 7/9 into the calculator at http://www.coolmath.com/graphit/and click "Eval" to visualize it.

(3x + 3y)(x + y) = 3(x + y)2
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
