What is 9x plus 27 equals -81?
9x+27 = -81 9x = -81-27 9x = -108 x = -12
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
What is x squared -9x squared?
- 8x2
