To solve such questions we must know about quadratic equations and factorization.
The quadratic equation can be factorized as (k+m)(p+3).
kp + 3k + mp + 3m
= (kp + 3k) + (mp + 3m)
Taking common from both the brakets,
= k(p+3) + m(p+3)
= (k+m)(p+3)
Hence, the quadratic equation can be factorized as (k+m)(p+3).
