Q. Pick the expression that matches this description:\newlineA polynomial of the 5th  5^{\text {th }} degree with a leading coefficient of 77 and a constant term of 66\newlineChoose 11 answer:\newline(A) 7x5+2x2+6 7 x^{5}+2 x^{2}+6 \newline(B) 6x5+x4+7 6 x^{5}+x^{4}+7 \newline(C) 6x7x5+5 6 x^{7}-x^{5}+5 \newline(D) 7x66x4+5 7 x^{6}-6 x^{4}+5
  1. Analyze options for 55^{\text{th}} degree polynomial: Analyze the given options to identify the polynomial of the 55^{\text{th}} degree.\newlineA polynomial of the 55^{\text{th}} degree must have its highest exponent as 55. This means we are looking for a term with x raised to the power of 55.
  2. Check if options meet criteria: Check each option to see if it meets the criteria of being a 55th-degree polynomial.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+6 - This is a 55th-degree polynomial.\newline(B) 6x5+x4+76x^{5}+x^{4}+7 - This is also a 55th-degree polynomial.\newline(C) 6x7x5+56x^{7}-x^{5}+5 - This is not a 55th-degree polynomial; it is a 77th-degree polynomial.\newline(D) 7x66x4+57x^{6}-6x^{4}+5 - This is not a 55th-degree polynomial; it is a 66th-degree polynomial.
  3. Identify 55th degree polynomial with leading coefficient of 77: Among the 55th-degree polynomials, identify the one with a leading coefficient of 77.\newlineThe leading coefficient is the coefficient of the term with the highest exponent.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+6 - The leading coefficient is 77.\newline(B) 6x5+x4+76x^{5}+x^{4}+7 - The leading coefficient is 66, not 77.
  4. Check constant term of remaining option: Check the constant term of the remaining option.\newlineThe constant term is the term without a variable.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+6 - The constant term is 66.
  5. Confirm option (A) meets all criteria: Confirm that option (A) meets all the criteria.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+6 is a 55th-degree polynomial with a leading coefficient of 77 and a constant term of 66.
