x2-7xy-18y2 Final result : (x + 2y) • (x - 9y) Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "y2"   was replaced by   "y^2".  1 more similar replacement(s).

Step by step solution : Step  1  :Equation at the end of step  1  : ((x2) - 7xy) - (2•32y2) Step  2  :Trying to factor a multi variable polynomial :

 2.1    Factoring    x2 - 7xy - 18y2 

Try to factor this multi-variable trinomial using trial and error 

 
Found a factorization  :  (x + 2y)•(x - 9y)

Final result : (x + 2y) • (x - 9y)
