Nice post manpansingh! Before anything, and to know why only (x-5) will be selected as a desired solution, one must have a basic understanding of mathematics, we all know that anything divided by zero is undefined,thus when we have x=3, x=2,x=1 then our denominator will be zero,, but since here thes...

IMO, as Socan said, there is no point retaining roots in the equations unless all the elements of the equation have an unknown factor , unless the given equation cannot be further simplified , unless we do not want to loose equation properties, and unless we find it amusing to solve polynomials For ...

Prime no -> any number that does not have a divisor other than 1 & itself Now, *7+3 = 3 x (1.2.4.5.6.7 + 1) -> This has more divisors other than 1 & *7+3 *7+4 = 4 x (1.2.3.5.6.7 + 1) -> This has more divisors other than 1 & *7+3 *7+5 = 5 x (1.2.3.4.6.7 + 1) -> This has more divisors othe...

Hi bblast I have a small issue with your approach. The question asks for the probability that it will rain on at least 3 days in a row during a 5 day period Also, IMO For Non Favorable outcomes that it will rain on any three days will not be 3/4 Probability that it rains exactly on no days = 1/32 Pr...
