You can put this solution on YOUR website! In a equation ,to find a variable( here P) try to find if there is any common variable.here there is only one variable that is P.
So, 5p-15p^2 = 0.
can be written as 5p( 1 - 3p) = 0(just simplifying the equation- taking the variable p and number 5 as common outside,when u multiply the 5p with the numbers inside the brackets that gives u back the equation).
now equate the term 5p = 0 and
1-3p =0
therefore the values of p are p =0
1-3p=0 gives p=1/3
