Grade 12th passAlgebrax+y+z+xy+yz+zx = 89 find the no of integral solutions? Viran 7 Years agoGrade 12th pass
Aditya Gupta6 Years agothis ques is wrong. correct ques should be x+y+z+xy+yz+zx+xyz = 89we can then solve it as follows:add 1 on both sides1+x+y+z+xy+yz+zx+xyz = 90or (1+x)(1+y)(1+z)= 90now this turns into a simple problem of finding the number of ways to factorise 90 into 3 factors.kindly approve :)
