1. Classical Algebra
1. In classical algebra, the degree of a polynomial is determined by:
A) The highest exponent of its variable.
B) The number of terms.
C) The coefficient of the leading term.
D) The constant term.
Answer: A
Explanation: The degree of a polynomial is the highest power of the variable present in the polynomial.
2. A binomial is a polynomial with:
A) One term.
B) Two terms.
C) Three terms.
D) Four terms.
Answer: B
Explanation: A binomial consists of two terms, typically separated by a plus or minus sign.
3. The leading coefficient of the polynomial 4x5−3x3+2x−74x^5 - 3x^3 + 2x - 74x5−3x3+2x−7 is:
A) 4
B) -3
C) 2
PAGE 2
, D) -7
Answer: A
Explanation: The leading coefficient is the coefficient of the term with the highest degree, which is 444 for
x5x^5x5.
4. The sum of the roots of the polynomial x2−5x+6=0x^2 - 5x + 6 = 0x2−5x+6=0 is:
A) 5
B) 6
C) -5
D) -6
Answer: A
Explanation: For ax2+bx+c=0ax^2 + bx + c = 0ax2+bx+c=0, the sum of roots is −b/a-b/a−b/a. Here,
−(−5)/1=5-(-5)/1 = 5−(−5)/1=5.
5. A monic polynomial is one where:
A) The constant term is 1.
B) The leading coefficient is 1.
C) All coefficients are positive.
D) It has only one term.
Answer: B
Explanation: A monic polynomial has its leading coefficient equal to 1.
6. The polynomial x3−2x+4x^3 - 2x + 4x3−2x+4 is of degree:
A) 1
B) 2
C) 3
