Question

The constant term in the product (𝑥 + 3) (𝑥 + 4) is

  1. 7
  2. 12
  3. 1
  4. -12

hintHint:

  • Multiplication polynomials
  • Multiply each term with each other.
  • Distributive identity:
  • a × (b + c) = ab + ac

The correct answer is: 12


    Answer:
    • Step by step explanation: 
      • Given:

    (x + 3) (x + 4)

    • Step 1:
    Product

    (x + 3) (x + 4)

    x (x + 4) + 3 (x + 4)
    [ a ( b + c) = ab + ac ]

    x2 + 4x + 3x + 12

    x2 + 7x + 12

    Hence, constant term is 12

    • Final Answer: 
    Correct option B. 12.
