(3p-x)^2=9p^2-6px+x^2=9p^2-566px-x^2-56=0X^2-6px+56=06px=18x p=3
Jo minus minus multiply kar ke minus kaise hua,hamre hain mein to minus,minus multiply karne se positive hots thaa,aap kis hain ke hain jee.
P=5
Sum of the factors is a multiple (NOT a factor) of 6
make p = + - 3 which will equate the condition of perfect square.
smallest) p=3
9p^2-56=(3p)^2-2.3p+1+6p-1-56=(3p-1)^2+6p-57 is a perfect square if and only if : 6p-57=0=>p=57/6=19/2=9.5. now check: 9×(9.5)^2-56=9×90.25-56=812.25-56=756.25=(27.5)^2. Verified found correct ans is p=9.5.
