let x be the p
x^2+11x+18
x^2+2x+9x+18
x(x+2)+9(x+2)
(x+2)(x+9)
x=-2and -9
substitute value of x as p in p+ q = 11 we will get answer
x^2+11x+18
x^2+2x+9x+18
x(x+2)+9(x+2)
(x+2)(x+9)
x=-2and -9
substitute value of x as p in p+ q = 11 we will get answer

pq=18, P=18/q, Putting, P+q=11 18/q+q=11 18+q2(q square)/q=11 18+q2=11q q2-11q+18=0 q2-9q-2q+18=0 q(q-9)-2(q-9)=0 (q-9)(q-2)=0 q=9,q=2
substitute both the values of q,you will get the value of p,ihad forgotten!
