Of which of the binomials given below is the m2n2+ 14mnpq + 49p2q� – InterviewSolution

1.

Of which of the binomials given below is the m2n2+ 14mnpq + 49p2q2 the expansion?(A) (m + n) (p + q) (B) (mn – pq) (C) (7mn + pq)(D) (mn + 7pq)

Answer»

(D) (mn + 7pq)

Here, square root of the first term = mn

Square root of the last term = 7pq

∴ Required binomial = (mn + 7pq)²
