MCQ
Which of the following is a binomial?
  • A
    $7 \times a + a$
  • B
    $6a^2 + 7b + 2c$
  • C
    $4a \times 3b \times 2c$
  • ✓
    $6 (a^2 + b)$
✓

Answer

Correct option: D.
$6 (a^2 + b)$
D.  $6 (a^2 + b)$
Solution:
Binomials are algebraic consisting of two unlike terms.
$7 \times a + a = 7a + a = 8a$ (monomial)
$6a^2 + 7b + 2c$ (trinomial)
$4a \times 3b \times 2c$ (monomial)
$6(a^2 + b) = 6a^2 + 6b$ (binomial)
