(9 - 5u)(9 + 5u)
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?
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 the 9th squared number number?
81
How do you factor 2xcubed minus x squared minus 162x minus 81?
I believe it is prime as you have written it. change the end to + 81 and it factors as (2x - 1)(x-9)(x+9)
