Question
The constant term in the product (𝑥 + 3) (𝑥 + 4) is
- 7
- 12
- 1
- -12
Hint:
- 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.
- Given:
[ a ( b + c) = ab + ac ]
Hence, constant term is 12
