What is the sum of the leading coefficient and the constant term of the expression 4x⁴ + 3x⁶ − x³ − 6x − 3?
Think it through first, then pick an option.
- a 0
- b 1
- c 3
- d 7
Answer and explanation
Correct answer: a 0
The leading coefficient is 3 (from 3x⁶) and the constant term is −3; the sum is 0.
Why the other options are wrong
- b 1: The sum is not 1; the leading coefficient is 3 and the constant term is −3, giving 0.
- c 3: 3 is only the leading coefficient; the constant term −3 must be added.
- d 7: 7 comes from adding 4 + 3 (the coefficients of x⁴ and x⁶); the leading coefficient is only the 3 of x⁶.
